Question

state 3 effects of force with example

Answer 1

Force causes wear and tear in machinery parts
eg- car tyres get worn out.

Force can stop an object.
eg- a car halts on being braked.

Force can move an object.
eg- a car moves on being accelerated.

Answer 2

Effects of Force

A force acting on an object causes the object to change its shape or size, to start moving, to stop moving, to accelerate or decelerate. When there’s the interaction between two objects they exert a force on each other, these exerted forces are equal in size but opposite in direction. When an object has several forces acting on it, the effects of force is same as one force acting on the object in a certain direction and this overall force is called the ‘resultant force’. The resultant force is essential to change the velocity of an object.

If the resultant force is zero the forces on the object are balanced.If the resultant force acting on the object is ‘zero’ then: the object will remain stationary. In such a case the object will move at a steady speed in a straight line.If the resultant force acting on the object isn’t zero then: the object will either accelerate or decelerate.

Solved Example For You

Q. When a football is kicked, its shape changes for a fraction of a second. This is because:

a. force changes the shape of an object

b. force does not change the shape of an object

c. momentum changes the shape of an object

d. motion changes the shape of an object

Sol: a. force changes the shape of an object

Force changes the shape of an object. When a football is kicked, a contact force is applied
and thus its shape changes.
