Force and Newton's Law

When swimming in a pool, gravity pushes you down. What keeps you from sinking?

• You don't weigh very much.
• Water currents
• The water putting an upward force on you
• gravity

If you are trying to find the MAGNITUDE OF ACCELERATION, what formula would you use?

• F=mxa
• A=F/m
• M=F/a
• S=D/T

If a rock and a piece of paper were dropped from the same height in a vacuum (with no air resistance), which one will hit the ground first?

• The rock
• The paper
• Neither 
• They will hit at the same time

What would be the rate of speed each second for a free-falling object? 

• 5 m/s
• about 10 m/s
• 0.1 m/s
• 0 m/s

What is the measure of the amount of gravitational force on an object on Earth?

• Weight
• Mass
• Inertia
• Energy

What formula do we use to find force?

• F=m/a
• F=a/m
• F=mxa
• P=fxa

What object will have the greatest inertia?

• A 1 kg object
• A 50 kg object
• A weightless object
• A 10 kg object

Which statement describes the weight of an object on Earth?

• The amount of space an object occupies
• The resistance an object has to its motion
• The objects mass
• The pull that gravity has on an object

How does an objects mass change how gravity effects it?

• Larger mass, the more gravitational force
• Smaller mass, the more gravitational force
• No change
• Larger mass, less gravitational force

What causes there to be different amounts of gravitational force on objects on Earth and the Moon?

• Less acceleration due to gravity on Earth?
• More acceleration due to gravity on the moon
• There would be no difference
• More acceleration due to gravity on Earth.
