PHYSICS 2 - REVIEWER

Question 1

states that an object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an external force.

Answer 1

Law of inertia

Question 2

What is the 2nd law of motion?

Answer 2

Force and Acceleration

Question 3

It is acting on an object is equal to the mass of the object multiplied by its acceleration.

Answer 3

Force

Question 4

It is a measure of the amount of matter in an object. It determines the object’s resistance to changes in motion.

Answer 4

Mass

Question 5

It is the rate at which an object’s velocity changes over time. It is directly proportional to the force applied and inversely proportional to the mass of the object.

Answer 5

Acceleration

Question 6

-In inelastic collisions, kinetic energy is not conserved.
-Objects stick together or deform after the collision.
-The total momentum of the system is conserved

Answer 6

Inelastic Collision

Question 7

Newton’s third law states that for every action, there is an equal and opposite reaction.

Answer 7

Law of action and reaction

Question 8

-kinetic energy is conserved.
-The total momentum of the system is conserved
-Objects bounce off each other and separate after the collision

Answer 8

Elastic Collision
