Force
What unit is force measured in?
Newtons
The more massive an object is, the ____ gravitational pull it has
more, greater, etc
A bowling ball going down the lane has what type of friction
Rolling friction
Describe Newton's First Law of Motion (can't just say "Law of Inertia")
answer will vary
Which type of friction acts on a box that is moving down a ramp?
gliding, rolling, sliding, static
sliding
A force is one of these two things.
Push or a pulll
less, weaker, etc
Pushing a dresser across the carpet is what type of friction
sliding
Describe Newton's Second Law of Motion
acceleration of an object depends on the mass of the object and the size of the net force applied.
Which is a force that keeps planets in orbit?
friction, inertia, gravity, speed
gravity
A force has these two qualities. (I need both for full credit)
If you have a mass of 120kg and a weight of 200 pounds on Earth, approximately, what would be your mass on the moon?
120kg, mass doesn't change
The friction just as an object begins to move is what type of friction
static
Describe Newton's Third Law of Motion
Which can be used to figure out the force needed to stop a moving object?
acceleration, friction, momentum, speed
momentum
Spring scale
Provide an example of gravity on Earth (can't use dropping an object)
answers will vary
Provide an example of helpful friction (nothing to do with fire)
answers will vary
What does Newton's first law say about a moving object if the forces on the object are balanced?
It will remain either at rest or in motion (depending on what it is currently doing)
Which is the unit of force?
m/s, kilogram, newton, km/h
newton
How do balanced forces affect the motion of an object?
It won't move because they are the same amount of force
Provide an example of gravity in outer space
answer will vary
Provide an example of harmful friction (no fire examples)
answers will vary
The combination of an object's mass and velocity in a given direction.
Momentum
An object weighs 100 N on Earth. Approximately how much would it weigh on the moon?
