Force, Motion, and Speed

Gravity

• a movement that involves a change in position or location of an object

• occurs when the net force on an object does not equal zero; results in the object changing its motion

• a force of attraction between objects that have mass

• sum of all forces acting on an object

Simple machine that consists of a flat, sloping surface (ramp)

• Simple Machine

• Inclined Plane

• Load

• Slope

An object’s tendency to resist change in motion

• Net Force

• Gravity

• Speed

• Inertia

Load

• the object to be moved using a machine

• amount of matter in something

• a device that makes work easier

• a measure of the force of gravity on an object

Amount of matter in something

• Unbalanced Force

• Position

• Mass

• Weight

A movement that involves a change in position or location of an object

• Position

• Motion

• Speed

• Work

Net Force

• a force of attraction between objects that have mass

• unit of measure of force

• sum of all forces acting on an object

• occurs when a force is used to move an object over a distance

Unit of measure of force

• Newton

• Resting Position

• Slope

• Net Force

An object’s distance and direction from a reference point

• Inertia

• Unbalanced Force

• Position

• Resting Position

Resting Position

• an object’s distance and direction from a reference point

• occurs when the net force on an object does not equal zero; results in the object changing its motion

• a movement that involves a change in position or location of an object

• a starting point used to locate another place or thing
