Force and Motion Unit Test

Balanced Forces

equal forces acting on an object, object will either be at rest or in a state of constant motion

Unbalanced Forces

Forces acting on an object that change the object's motion

Newton's 1st Law of Motion

An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.

Inertia

the tendency of an object to remain in motion or at rest

Force

a push or pull on an object

Magnitude

The strength of a force acting on an object

Gravity

The force that pulls objects towards Earth

Slope on a distance-time graph

Represents speed of an object

Constant Speed

represented by a straight diagonal line on a distance-time graph

Speed Equation

Speed = Distance / Time

Velocity

Speed and direction of an object

Zero Slope

A flat line on a distance-time graph that represents an object at rest

Distance

The path an object takes to get from point A to point B

Displacement

A straight line connecting point A to point B
