An overall force acting on an object.

Answer 3

Net Force

Question 4

When 2 or more objects are pushing on another object with the same amount of force.

Answer 4

Balanced Force

Question 5

When one object is pushing on another object with more force than the other.

Answer 5

Unbalanced Force

Question 6

The resistance of an object to a change in speed or direction of its motion.

Answer 6

Inertia

Question 7

A scientific law that states that the acceleration of an object increases with increased force and vise versa.

Answer 7

Newtons Second Law

Question 8

Any force that keeps an object moving in a circle.

Answer 8

Centripetal Force

Question 9

A scientific law that states that every time one object exerts a force on another, the second object exerts a force that is same in size but in the opposite direction.

Answer 9
