Newtons Laws

Front

What are the appropriate units to describe acceleration?

Back

m/s² (meters per second squared)

Front

If an object has twice as much mass as another, then it also has twice as much:

Back

Weight

Front

What does Newton's first law state?

Back

An object at rest will remain at rest unless a force is applied.

Front

In referring to how much matter a body contains, we use the term:

Back

Mass

Front

What is Newton's third law?

Back

For every action, there is an equal and opposite reaction.

Front

What is the formula for calculating weight?

Back

Weight = Mass × Acceleration due to gravity (W = m × g)

Front

What is inertia?

Back

Inertia is 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, proportional to its mass.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object; weight is the force of gravity acting on that mass.
