13. What is the horse doing to
the cart?
How does that force affect
We cannot see force, but the effects of the force can. We show the direction of the force as arrows

14. What is gravitational force?
Gravity ; is a force of attraction between two objects .
Gravity depends on two factors
1- Mass ( Mass increased- gravity increase )
2- Distance ( Distance increase- gravity decrease )
