• Newtons ____ Law is also known as the Law of
Inertia.
• Newtons 1st Law- an object in motion tends to
stay in motion and an object at rest tends to
stay at rest unless acted upon by an outside
force.

3 - 500
• Why does a person weigh less on the moon than on
Earth?
• a/ There is no gravity on the moon
• b/ A person has less mass on the moon
• c/ There is less gravity on the moon because the
moon has less mass than Earth.
• c/ There is less gravity on the moon because the
moon has less mass than Earth.

4 - 500
• Which of Newtons Laws is also known as the Law
of Inertia?
• Newtons 1st Law An object in motion tends to
stay in motion and an object at rest tends to
stay at rest unless acted upon by an outside
force.
