8th Grade Forces & Motion

Front

Newton's Second Law

Back

The acceleration of an object is equal to the net force acting on the object divided by the object's mass.

Front

Balanced Force

Back

A force that does not cause an object to move.

Front

Speed vs. Time Graph (2-5 seconds)

Back

The object is moving at a constant speed.

Front

Effect of Mass on Gravity

Back

The larger the mass of the object, the greater the gravity.

Front

Centripetal Force

Back

The force that pulls an object in a circular motion and keeps it in a circular motion.

Front

Newton's First Law

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

Unbalanced Force

Back

A force that causes an object to accelerate or change its motion.

Front

Friction

Back

A force that opposes the motion of an object.

Front

Inertia

Back

The tendency of an object to resist changes in its state of motion.

Front

Acceleration

Back

The rate of change of velocity of an object.
