What is force and energy?

Dear student,
A push or pull is called force. For example, when you push the door , it means that you are applying force on it. One more example of force can be , when you throw a ball in air, it returns back to the ground, this happens only because our earth applies a pulling force on the ball.
Energy: in simple words we can say that energy is the ability to do work. Energy is how things change and move. It's everywhere around us and takes all sorts of forms. It takes energy to cook food, to drive to school, and to jump in the air.
Regards
