Gravity is a pulling force between two objects
True
False
Any object with mass experiences gravity
True
False
Why do astronauts bounce so high on the moon?
The moon has more gravity
The moon has less gravity
Objects with more mass have a stronger gravitional pull.
True
False
Earth's gravity pulls everything toward:
North
South
East
The center of the earth
Gravitational force is smaller between
Larger objects
Smaller objects
As distance increases ( go farther away) , gravitational forces:
Decrease
increase
Disappear
Stay the same
As mass increases, gravitational forces:
Increase
decrease
stay the same
disappear
A measure of gravitational force is:
weight
mass
newtons
watts
Why doesn't the sun pull us off the earth?
It is too small
It is too far away
It is too big
It is too close
What is gravity?
The force that pulls objects together
The force that pushes objects apart
YES, Gravity's force determines your weight.
NO, you always weigh the same.
Which two factors determine how strong the gravitational force is.
When you drop a hammer and a feather on Earth, why does the feather fall slower?
air resistance causes the feather to slow down
gravity pulls harder on the hammer than the feather
gravity pulls harder on the feather than the hammer
air resistance causes the hammer to fall slower
TWO of these forces act on parachutes.
Air Resistance
Gravity
Thrust
Kinetic Energy
What causes an object to fall faster?
Smaller surface area
Larger surface area
If it has a parachute
If it is softer
The larger the surface area of the moving object, the ___________ air resistance there is.
Less
More
Longer
Quicker
