Forces and Motion

Front

What does a motion graph that is flat represent?

Back

A body at rest.

Front

What effect does friction have on a moving object?

Back

It causes the moving object to slow and eventually stop.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest and an object in motion stays in motion until acted upon by an unbalanced force.

Front

What is the definition of motion?

Back

A change in an object's position, direction, or location.

Front

What is a contact force?

Back

A force that arises from objects physically touching each other.

Front

What is inertia?

Back

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

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is gravitational force?

Back

The attractive force between two objects due to their mass.
