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 the 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.
