Force in one dimension

Front

Inertia

Back

The tendency of an object to resist changes in velocity.

Front

Force

Back

A push or pull exerted on an object.

Front

Newton's First Law

Back

States that an object at rest will remain at rest, and a moving object will continue moving in a straight line with constant speed, if and only if the net force acting on that object is zero.

Front

Normal Force

Back

The perpendicular contact force exerted by a surface on another object.

Front

Weight Force

Back

The force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (W = mg).

Front

Frictional Force

Back

The force that opposes the motion of an object in contact with a surface.

Front

Tension Force

Back

The force transmitted through a string, rope, or wire when it is pulled tight.

Front

Net Force

Back

The vector sum of all the forces acting on an object.

Front

Mass

Back

A measure of the amount of matter in an object, typically measured in kilograms.

Front

Acceleration

Back

The rate of change of velocity of an object, calculated as the change in velocity divided by the time taken.
