12
Two objects collide and the collision is ELASTIC, which is TRUE
Momentum is conserved
Momentum is not conserved
The forces they exert on each other are equal
Kinetic energy is not conserved
13
In physics, speed (and velocity) are measured in what units?
Miles per hour
Newtons times meters
Meters per second squared
Meters per second
14
How can acceleration be produced when the linear speed is constant?
By going in a circle WITH a changing radius
It cannot, this is a trick question
By the object going in a straight line
By the object constantly changing its direction
15
How is velocity different from speed in physics?
Velocity has a direction
Speed has a magnitude
Velocity has a magnitude
Speed has a direction
16
A vector in physics has
Only a direction
Only a magnitude
Neither a direction or a magnitude
Both a direction and a magnitude
17
Google fiber (a.k.a. fiber optics) works by using
Pulses of electrons through glass fibers
It doesn't work, Comcast (Xfinity) is telling the truth
Pulses of sound through glass fibers
Pulses of light through glass fibers
18
To objects collide and the collision is inelastic. Which is true?
The objects stick together
Momentum is not conserved
The objects bounce off each other
Kinetic energy is conserved
19

Gravity
Force
The Newton
Inertia
21
What brand is this logo?
Porshe
Audi
Mercedes
BMW
22
Why do astronauts in the space station orbiting the Earth experience no weight?
Because there is more gravity in space
This is false, the space station produces its own gravity
Because they are, in fact, falling toward the Earth
Because there is no gravity in space
23
Linear momentum depends on which of these?
Electric charge
Mass
Acceleration
The speed of light
24
Which of these would violate the law of conservation of momentum?
