Question
Answer the following in detail.
What are the various effects of force? State one example of each.
Solution
Various effects of force :
- A force can move a stationary object.
Example: Pulling a suitcase on its wheels. - A force can stop a moving object.
Example: A ball rolling on the rough surface comes to rest after some time due to the force of friction. - 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. - 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. - 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.
