What determines an object’s mass?
amount of matter
amount of friction
amount of force

All of the above
While you’re ice-skating with your friends, you push off from one end of the rink and slide forward. Based on Newton’s first law of motion, what is true?
You will lose your balance and fall over before your reach the middle of the ice rink.
You will continue to slide across the ice until a force makes you stop or change direction.
The force of gravity will make you keep your velocity until your friends make you stop.
The size of your ice skates will determine how quickly or slowly you travel across the ice.
What does friction do to a moving object?
Makes it rise
Slows it down
Speeds it up
All of the above
How is velocity different from speed?
Velocity is when an object goes in reverse.
Velocity is the direction an object moves in, and it has nothing to do with speed.
Velocity is speed and direction together.
Velocity is not at all different from speed.
A force can____________.
make an object move
make a moving object stop moving
slow an object down
all of the above
True or false: An object resting on the ground can move without force.
True
False
What does the force of gravity do to objects?
It makes them float
it makes them jump
it pulls them to the center of earth
it pushes them apart
An example of the force of gravity is-
a rocket flying through space
a ball falling to the ground after it has been thrown
a cloud moving across the sky
the Sun rising
What is Newton's First Law of Motion?
F=M X A
The Law of Inertia
Force means a push or pull
You must clean up Gail's classroom daily.
What is Inertia?
An object at rest will move and an object in motion will stop.
Objects are lazy.
An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an outside force.
F=M X A
A squid moves through the water by ejecting water out of its body into the surrounding water. When the water is pushed out, the ejected water pushes back and thrusts the squid forward.
First Law of Motion (law of inertia)
Second Law of Motion (law of force and acceleration)
Third Law of Motion (law of motion and reaction)
Fourth Law of Motion (law of balanced forces)
