3. Forces
A force can be a push or a pull. It is not something you can see or touch, but can see it in action . The unit of force is called the Newton.

5. Contact force
In physics, a contact force is a force that acts at the point of contact between two objects. Contact forces are described by Newton's laws of motion, as with all other forces in dynamics.

7. Non – contact force
A non-contact force is a force applied to an object by another body that is not in direct contact with it. The most familiar example of a non-contact force is weight.

9. The force of gravity
The force of gravity is the force exerted by the gravitational field of a massive object on any body.

10. Air Resistance Force
The air resistance force is a special type of frictional force that acts upon objects as they travel through the air.
