1.	What are the various effects of force ? State one example of each.
Answer» 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 rough surface comes to rest after some time due to 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.
