Unit 3 Review

  a push or pull exerted by one object or another, possibly causing a change in motion

• motion
• force
• friction

a change in an object's position compared to a reference point.

• motion

• force

• friction

how fast an object's position changes with time

• speed
• velocity
• acceleration

the location of an object compared with things around it

• motion
• distance
• position

a force that opposes the motion of an object in contact with a surface/ Otherwise when two forces rub against each other.

• motion

• force

• friction

the length between two places

• distance
• position
• speed

the tendency of a moving object  will continue to move in a straight line

• velocity
• position
• inertia

a physical law stating that an object tends to stay at rest and an object moving in a straight line at a constant speed tends to continue moving that way

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

a physical law stating that an object's acceleration depends on the object's mass and the amount of the net force applied to it

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law

a physical law stating that for every action there is an equal and opposite reaction

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
