Answer 5

Vector

Question 6

The rate at which velocity changes over time.

Answer 6

Acceleration

Question 7

A push or a pull; something that changes the motion of an object.

Answer 7

Force

Question 8

The overall force acting on an object when all of the forces acting on it are combined.

Answer 8

Net Force

Question 9

A scientific law stating that objects at remain at rest, an objects in motion remain in motion with the same velocity, unless acted on by an unbalanced force.

Answer 9

Newton’s First law

Question 10

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

Answer 10

Inertia

Question 11

A scientific law stating that the acceleration of an object increases with increased force and decreases with increased mass.

Answer 11

Newton’s Second law

Question 12

Any force that keeps an object moving in a circle.

Answer 12

Centripetal Force

Question 13

A scientific law stating that every time an object exerts a force on another object, the second object exerts a force that is equal in size and opposite in direction back on the first object.

Answer 13

Newton’s third law
