What force works against a skateboarder's inertia when they launch off a ramp?

Back

Gravity

Front

What two pieces of information are needed to describe the velocity of a moving car?

Back

Speed and direction

Front

What is the energy of motion also known as?

Back

Kinetic energy

Front

What is the relationship between mass and inertia?

Back

Inertia is directly proportional to mass; more mass means more inertia.

Front

What is Newton's First Law of Motion?

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

What is the formula for calculating force?

Back

Force = mass × 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 potential energy?

Back

The energy an object possesses due to its position in a gravitational field, calculated as mass × gravity × height.
