Give two examples of situations in which applied force causes a change in the shape of an object.
The shape of an object can be changed due to applied force. For example:
1. When force is applied on a lump of dough on a plate.
2. The spring fitted under the seat of a bicycle gets compressed when you sit on the seat.
A charged body ____________ an uncharged body towards it.
To move a loaded trolley we have to ____________ it.
The north pole of a magnet ____________ the north pole of another magnet.
