What happens to objects falling on the moon because it has less mass than Earth?
They fall slower due to lower gravity.
They fall faster due to lower gravity.
They do not fall at all.
They fall at the same rate as on Earth.
What determines gravitational pull?

Temperature and pressure
Speed and velocity
Color and texture
The effect of gravity that keeps objects moving in a circular path is known as:
Centripetal force
Centrifugal force
Gravitational pull
Inertia
What happens to an object's gravitational pull if its mass increases?
It decreases
It remains the same
It increases
It disappears
Earth’s gravity pulls on the moon and keeps it in orbit. What does the moon’s gravity do?
It has no effect on Earth.
It pulls on Earth, affecting tides.
It pushes Earth away.
It keeps Earth stationary.
Which force keeps the planets in orbit?
Electromagnetic force
Nuclear force
Gravitational force
Frictional force

What can slow something down if it is dragged across the ground?
Friction
Gravity
Momentum
Inertia
What is the difference between kinetic friction and static friction?
Kinetic friction is greater than static friction.
Static friction is greater than kinetic friction.
Both are equal.
Kinetic friction does not depend on the surface.
What force acts on an object in free fall?
Gravity
Friction
Magnetism
Electricity
How does the gravitational pull of the moon affect earth?

It causes tides in the oceans.
It has no effect on Earth.
The force of gravity (mass x gravity) is also known as...
mass
weight
distance
acceleration
