Newton's Laws

Front

What do the letters F, m, and a represent in Newton's Second Law of Motion?

Back

F = Force, m = Mass, a = Acceleration

Front

If a dog travels 56 m South in 2 hours, what is his velocity?

Back

28 m/h South

Front

What law of motion describes the action-reaction principle?

Back

Newton's 3rd Law of Motion

Front

What is an example of an unbalanced force?

Back

A car accelerating on a highway

Front

What are the units for measuring mass?

Back

Kilograms

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

F = m * a (Force = Mass x Acceleration)

Front

What does acceleration measure?

Back

The rate of change of velocity of an object.

Front

What is inertia?

Back

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

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight = Mass x Gravity.
