In 1969, Neil Armstrong became the first person to walk on the Moon. Video coverage showing the astronaut walking on the surface of the Moon gives the impression that he was bouncing while he walked. What is the reason for this?
The astronaut's mass on the Moon decreases.
The density of the astronaut on the Moon is higher than on Earth.
The atmosphere of the Moon affects the way the astronaut is able to move.
The astronaut's weight on the Moon depends on the Moon's gravitational force.

An apple falling on your head is an example of what?
Applied Force
Magnetism
Friction
Gravity
The more mass an object has, the greater the gravitational force between it and other objects.

Depends on the environment
What is the definition of Mass?
the measure of an object from top to bottom
the weight of an object
the measure of an amount of matter in an object
How does distance impact gravitational force?
As distance decreases between two objects, the gravitational force will decrease.
As distance increases between two objects, the gravitational force will decrease.

Which is NOT true about sound waves?
A sound wave travels by the compression of molecules as it travels through a medium.
Sound waves travel as Electromagnetic Radiation.
Sound causes compression waves from side to side in matter.
The closer the molecules, the faster sound can travel.
When a light wave bounces off a surface and changes its direction.
