Write a note on effect of force
Answers
Answer:
Force can set a stationary object in motion:
When force is applied on a stationary object, the object tends to move in the direction in which force is applied. For example, applying force on a stationary tennis ball will make it continue its motion in the direction of applied force.
Force can either stop or slow down the moving object:
Force needs to be applied on a moving object either to stop it or to slow down the object. For example, the moving ball can be stopped by applying external force.
Force is applied to change the direction of moving object:
The direction of a moving object can be changed by applying the force on that object. For example, the direction of the moving football can be changed by applying force at an angle such that the direction is changed.
The shape of an object can be changed by applying force:
Consider a rod which is circular in shape, by hammering the rod which is applying an external force, the rod can be turned into a flat sheet.
Answer:
A push or a pull acting on an object is called force. The SI unit of force is newton (N). We use force to perform various activities. In common usage, the idea of a force is a push or a pull
