Basic Physics Concepts

Front

Force

Back

A push or a pull acting on an object

Front

Reference Point

Back

The motion of an object is always judged with respect to some other object or point. The other object or point is known as the reference point.

Front

Speed

Back

A measure of how quickly an object gets from one place to another, mathematically represented by distance divided by time.

Front

Net Force

Back

The sum of all the forces acting on an object.

Front

Unbalanced Force

Back

Net force acting on an object that changes the object’s speed, direction of motion, or both.

Front

Balanced Force

Back

Net force acting on an object that does not change the object’s speed or direction of motion.

Front

Friction

Back

A force that opposes motion between two surfaces that are in contact.

Front

Inertia

Back

The tendency of objects to resist any change in motion.

Front

Velocity

Back

Speed with a given direction.

Front

Motion

Back

When an object changes position over time relative to a reference point.
