What lunar phase does a solar eclipse occur?

Back

A solar eclipse occurs during the New Moon phase.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

How does weight relate to mass and gravity?

Back

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

Front

What is the net force when two forces of 60N and 0N act in the same direction?

Back

The net force is 60N in that direction.

Front

What lunar phase does a lunar eclipse occur?

Back

A lunar eclipse occurs during the Full Moon phase.

Front

What is the formula for calculating net force?

Back

Net Force = Total Forces acting in one direction - Total Forces acting in the opposite direction.

Front

What happens to a boulder's weight on different planets?

Back

A boulder's weight changes depending on the gravitational pull of the planet.

Front

What is the difference between mass and weight?

Back

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

Front

What is an example of Newton's 1st Law of Motion?

Back

An object at rest stays at rest unless acted upon by an external force.

Front

What is an example of Newton's 2nd Law of Motion?

Back

F = ma (Force equals mass times acceleration).
