Newton’s First Law Examples in Everyday Life

Newton’s First Law Examples in Everyday Life

Newton’s first law states that an object at rest remains at rest and an object in motion remains in motion (with the same speed and in the same direction) unless an unbalanced force acts on it.

This law is also known as the law of inertia.

Here are some examples of newton’s first law in everyday life:

  • #1 Stationary football will not move unless someone kicks it
  • #2 Moving football will not stop unless something stops it
  • #3 Stationary car will not start unless someone starts it
  • #4 Moving car will not stop unless something stops it
  • #5 Stationary puck will not move unless someone hits it
  • #6 Moving puck will not stop unless something stops it
  • #7 Stationary bicycle will not move unless someone rides it
  • #8 Moving bicycle will not stop unless something stops it
  • #9 Stationary billiard ball will not move unless someone hits it
  • #10 Moving billiard ball will not stop unless something stops it
  • #11 Stationary bowling ball will not move unless someone throws it
  • #12 Moving bowling ball will not stop unless something stops it
  • #13 Stuck tomato ketchup will not come out unless someone hits the bottle
  • #14 Stationary scooter will not move unless someone starts it
  • #15 Moving scooter will not stop unless something stops it
  • #16 Astronaut floating in outer space will not stop unless something stops it
  • #18 Asteroid floating in outer space will not stop unless something stops it

Let’s one by one discuss the above examples in detail.

#1 Stationary football will not move unless someone kicks it

Think of one stationary football lying on the ground. What do you think, will this football move on its own? Nope. You must have to kick it or push it, right! As per Newton’s first law, the stationary football (object) will not move on its own unless an unbalanced force acts on it.

#2 Moving football will not stop unless something stops it

Newton's First Law Example - Moving Football

When you throw or kick the football, you’re applying an external force that makes a football move from rest. Similarly, a flying football will also not stop on its own unless an unbalanced force (for example, some other player) stops it.

#3 Stationary car will not start unless someone starts it

Newton's First Law Example - Stationary Car

According to Newton’s first law, an object at rest will continue to remain at rest unless an unbalanced force makes it move. A stationary car standing on the road will not start on its own unless someone starts it with a key or maybe an unbalanced force (in the form of someone’s push) acts on it.

#4 Moving car will not stop unless something stops it

Newton's First Law Example - Moving Car

While you’re driving a car, your car is in motion. Newton’s first law says that if no external force acts on an object, then an object will continue to remain in motion forever. Here, this moving car will not stop on its own unless an unbalanced force (for example, brakes) stops it.

#5 Stationary puck will not move unless someone hits it

Newton's First Law Example - Stationary Puck

Is a hockey puck an example of Newton’s first law? Yes. Here’s how:

Imagine that one hockey puck is resting on ice. According to the first law, an object (in this case, a hockey puck) will not move on its own unless an unbalanced force acts on it. When a hockey player hits a stationary puck, an unbalanced force of a hockey stick will make a puck move from rest.

#6 Moving puck will not stop unless something stops it

Newton's First Law Example - Moving Puck

Even after a stationary puck comes in motion, it will not stop on its own unless something (for example, some other player’s hockey stick) stops it. Newton’s first law tells the same thing, a moving object will not stop on its own unless an unbalanced force stops it.

#7 Stationary bicycle will not move unless someone rides it

Newton's First Law Example - Stationary Bicycle

A stationary bicycle parked in the garden will not move on its own unless someone rides it. An unbalanced force applied on a bicycle pedal with the leg will make a stationary bicycle move from rest. And this is Newton’s first law (objects don’t change their position on their own unless an unbalanced force acts on them).

#8 Moving bicycle will not stop unless something stops it

Newton's First Law Example - Moving Bicycle

Newton’s first law says that if no external force acts on an object, then an object will continue to remain in motion forever. Here, a moving bicycle will not stop on its own unless an unbalanced force (for example, brakes) stops it. This thing shows the presence of the first law.

#9 Stationary billiard ball will not move unless someone hits it

Newton's First Law Example - Stationary Billiard Ball

You might have seen a billiard ball resting on the pool table. Have you ever wondered why the ball does not move on its own? That’s because of Newton’s first law. A billiard ball will not move on its own unless someone hits it with the stick.

#10 Moving billiard ball will not stop unless something stops it

Newton's First Law Example - Moving Billiard Ball

A billiard ball will come in motion when you hit it with the stick. And as per Newton’s first law, this billiard ball will not stop on its own unless an unbalanced force acts on it (for example, when it hits another billiard ball or on the table’s edge).

#11 Stationary bowling ball will not move unless someone throws it

Newton's First Law Example - Stationary Bowling Ball

Newton’s first law says that objects don’t change their position on their own unless an unbalanced force acts on them. Here also, the same thing happens. A stationary bowling ball will not move towards the pin on its own unless an unbalanced force makes it move (for example, when someone throws it with the hand).

#12 Moving bowling ball will not stop unless something stops it

Newton's First Law Example - Moving Bowling Ball

According to the first law, a moving object will continue to move forever unless an unbalanced force stops it. Here, a moving bowling ball thrown towards the pin stops when it strikes with the bowling pin (i.e., the strike of a bowling ball with the bowling pin acts as an unbalanced force).

#13 Stuck tomato ketchup will not come out unless someone hits the bottle

Newton's First Law Example - Tomato Ketchup

You might have seen that sometimes, tomato ketchup gets stuck inside a ketchup bottle, and it does come out on its own (unless gravity pulls it downwards or it comes out when you hit a ketchup bottle from the backside with your hand). This thing clearly shows the presence of the first law.

#14 Stationary scooter will not move unless someone starts it

Newton's First Law Example - Stationary Scooter

As per Newton’s first law, objects don’t change their position on their own unless an unbalanced force acts on them. A stationary scooter parked on the road will not move on its own unless someone starts and rides it. When someone starts a scooter with a key, an unbalanced force (applied by the engine) acts on a scooter, and due to this, a stationary scooter will move from rest.

#15 Moving scooter will not stop unless something stops it

Newton's First Law Example - Moving Scooter

While driving a scooter, you may have experienced that if you don’t apply the brakes to a moving scooter, then your scooter will continue to remain in motion. However, the force of friction (which acts as an unbalanced force) eventually slows down a moving scooter.

#16 Astronaut floating in outer space will not stop unless something stops it

Newton's First Law Example - Astronaut

Newton’s first law says that objects don’t stop on their own unless an unbalanced force stops them. The same thing happens with astronauts in outer space. In space, astronauts continue to float forever since there is a lack of gravity. Therefore, unless they get hit by another object, they do not get stopped on their own.

#17 Asteroid floating in outer space will not stop unless something stops it

Newton's First Law Example - Asteroid

When an asteroid is floating in outer space, it is in motion. And, as per Newton’s first law, this asteroid will continue to remain in motion forever if no unbalanced force acts on it. (i.e., unless an asteroid gets hit by another celestial body or enters the other planet’s gravitational field, it will continue to move in outer space forever)
