Newton's Laws of Motion (Newton's Laws of Motion and Forces)

What is the only thing that can make an object move?

• a force

• inertia

Removing air takes away what force?

• friction

• gravity

Wait, why are the markers flying upward?

• They are less dense than air

• They had inertia in the upward direction and want to continue moving that direction when the board stopped moving.

• They are lighter than air so they float to the top of the room.

Newton's first law basically says

• objects will not change their state of motion unless a new force is applied

• objects that have forces will slow down

If two blocks have the same mass, twice the force results in

• accelerating twice as much

• accelerating half as much

More mass and same foce results in

• more acceleration

• more speed

• less acceleration

Mass and weight are the same thing.

• false

• true

Weight is caused by

• mass alone

• the force of gravity and mass

In a vacuum (like in outer space)

• air resistance is a space force that opposed motion.

• there is no air resistance.

Your weight pushing down on the chair (action) has a reaction force pair of

• gravity holding you up

• the chair pushing back on you
