Basic Physics Concepts

Front

Simple Machines

Back

Devices that make work easier by allowing us to push or pull over increased distances. Examples include levers, pulleys, and inclined planes.

Front

Force

Back

A push or pull upon an object resulting from the object's interaction with another object.

Front

Motion

Back

The change in position of an object over time.

Front

Lever

Back

A rigid bar resting on a pivot, used to help move a heavy or firmly fixed load with one end when pressure is applied to the other.

Front

Wedge

Back

A piece of material, such as metal or wood, thick at one end and tapering to a thin edge at the other, used for splitting, lifting, or tightening.

Front

Gravity

Back

The force that attracts a body toward the center of the earth, or toward any other physical body having mass.

Front

Inclined Plane

Back

A flat surface set at an angle to help raise or lower objects with less effort.

Front

Pulley

Back

A wheel with a grooved rim in which a rope can run to change the direction of the force applied to move a load.

Front

Friction

Back

The resistance that one surface or object encounters when moving over another.
