__________________ is something that is not moving with respect to an observer and can be used to detect motion.
What is a frame of reference?
100
A measure of the change in velocity of a moving object.
What is acceleration?
100
Push or pull acting on an object.
What is force?
100
Overall force acting on an object that takes into account all the individual forces.
What is net force?
100
Counter force excerted by an elastic material when it is stretched or compressed.
What is elastic force?
200
Change in position.
What is motion?
200
Measure of both speed and direction of motion.
What is velocity?
200
Motion of an object that has initial horizontal velocity but is also pulled down toward Earth by gravity.
What is projectile motion?
200
SI unit for force
What is Newton?
200
Measure such as velocity that includes both size and direction.
What is vector?
300
How quickly or slowly something moves.
What is speed?
300
Law stating that gravity is a force of attraction between all objects in the universe and that the strength of gravity is greater when masses of objects are greater or distances between objects are shorter.
What is the law of universal gravitation?
300
The ability of a material to return to its original shape after being stretched or compressed.
What is elasticity?
300
Substance that flows and takes the shape of its container.
What is fluid?
300
Force that opposes motion between two surfaces that are touching.
What is friction?
400
Name the types of friction and give an example of each.
What are static friction (rubbing hands together), sliding friction (writing with a pencil), rolling friction (roller skates), fluid friction (oil in a car to lubricate parts)?
400
List 3 uses of elastic force.
What are rubber bands, hair scrunchies, elastic waistbands, etc.?
400
Length of the route between two points.
What is distance?
400
Path of one object around another, such as the path of the moon around Earth or of Earth around the Sun.
What is an orbit?
400
As traditionally defined, force of attraction between things that have mass.
What is gravity?

A roller coaster car rapidly picks up speed as it rolls down a slope. As it starts down the slope, its average speed is 4 m/s. 3 seconds later, at the bottom of the slope, its speed is 22 m/s. What is its average acceleration?
What is 6 m/s^2?
