In physics, a force is defined as a push or pull exerted on an object. It is an interaction that can induce a change in the object’s motion. The presence of a force is observed whenever two objects interact with each other.
When a toy train, attached to a thread, is pulled by hand while resting on the floor, an interaction occurs between the hand and the thread. This interaction generates a force that propels the toy train forward. Thus, the hand exerts a force on the toy train to initiate its movement.
When someone kicks a ball with their leg, a force is applied to the ball, causing it to move forward. This force is generated through the interaction between the leg and the ball. Therefore, when a ball is kicked with the leg, there is a force exerted by the leg on the ball.
Glass of water
Consider a glass of water placed on a desk. When a hand is used to pick up the glass, a force is exerted on it. The force of the hand acts on the glass of water, allowing it to be lifted and moved.
When a horse pulls a cart, an interaction between the horse and the cart generates a force that propels the cart forward. This force, exerted by the horse, enables the cart to move.
When a person strikes a punching bag with their fist, an interaction occurs between the fist and the bag. This interaction results in a force that causes the punching bag to move forward and be displaced. Thus, when a person hits a punching bag, there is a force exerted by the fist onto the bag.
When closing a door with your hand, an interaction occurs between your hand and the door. This interaction results in a force that causes the door to move and close. Therefore, when you close a door with your hand, there is a force exerted by your hand on the door.
When a trolley is pushed by hand, a force is applied. The interaction between the hand and the trolley generates this force, causing the trolley to move forward. Thus, the hand exerts a force on the trolley when it is pushed.
When a dumbbell is lifted by hand, a force is exerted on it. The interaction between the hand and the dumbbell generates this force, resulting in the upward movement of the dumbbell. Therefore, when someone lifts a dumbbell with their hand, there is a force of the hand acting on the dumbbell.
In a typical situation, opening a window with a hand involves the application of force. When a window is opened using a hand, an interaction occurs between the hand and the window, resulting in a force being exerted. It is a general principle that when two objects interact, a force is present. Hence, when a window is opened or closed with a hand, a force from the hand acts upon the window.
