Question

What are the various effects of force? State one example of each.

Answer 1

Various effects of force :

$1.$ A force can move a stationary object. Example: Pulling a suitcase on its wheels.

$2.$ A force can stop a moving object. Example: A ball rolling on a rough surface comes to rest after some time due to the force of friction.

$3.$ A force can change the speed of a moving object. Example: We can increase the speed of a moving swing, we apply a force (push) in the direction of motion to increase its speed.

$4.$ A force can change the direction of a moving object. Example: A moving bicycle changes its direction when a force is applied to steer its handle.

$5.$ A force can change the shape and size of an object. Example: When we make a chapatti, a small ball of dough is changed to a flat, circular shape of a much bigger size by applying a force with the help of a rolling pin.
