Gravitational Force and Air Resistance

Air resistance pushes against falling

objects and __________________.

• Speeds them up

• Keeps them afloat

• Slows them down

• Spins them

• Force and gravity

• Gravity and Air Resistance

An example of a gravity is that the Earth... 

• orbits the sun
• orbits the moon
• orbits other planets 
• none of the above

A person would weigh more on Jupiter than on the Earth because . . .

• Jupiter has more mass, and therefore more gravity
• Jupiter has less mass, and therefore more gravity
• Jupiter has more mass, and therefore less gravity
• Jupiter has less mass and therefore less gravity
