What does a graph showing an object moving away from the start at a constant speed indicate?

Back

The object is increasing its distance from the starting point at a steady rate.

Front

Which of Newton's Laws explains why a roller coaster doesn't need a motor?

Back

Newton's First Law states that an object in motion stays in motion unless acted upon by an external force.

Front

What is a scalar quantity?

Back

A scalar quantity is a physical quantity that has magnitude but no direction, such as weight or temperature.

Front

Define free falling.

Back

Free falling is the motion of an object falling under the influence of gravity with no other forces acting on it.

Front

What happens to power if you increase work and decrease time?

Back

You will have more power.

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that 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 power?

Back

Power = Work / Time.

Front

What is the difference between a vector and a scalar quantity?

Back

A vector quantity has both magnitude and direction, while a scalar quantity has only magnitude.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
