The speedometer on a car tells you this

What is instantaneous speed?

100

Resistance to change in motion

What is inertia?
100

∆momentum or mass x ∆velocity or force x ∆time

What is impulse?

100

In the diagram below, in which position is the gravitational potential energy the greatest?


position A

100

Number of rotations or revolutions per unit time

What is rotational speed (or angular speed)?

200

A quantity with both magnitude and direction

What is a vector quantity?

200

This quantity does not change for an object - whether on Earth, the moon, or in deep space (in other words - independent of gravity)

What is mass (or inertia)?

200

In a head on collision between a Smart car and a fully loaded truck... (don't worry about wording as question) 

Force of the Smart car on truck = Force of the truck on the Smart car

200

In the diagram below, in which position is roller coaster's speed the greatest?

Position D

200

The force that keeps objects moving in a circle and the direction of that force.

What is centripetal force? which always acts in the direction towards the center of the circle.

300

Speeding up, slowing down, or changing direction

What is acceleration?

300

When acceleration = 0 m/s/s, Net force = 0 N, Force of friction = force of push, and velocity is constant

What is mechanical equilibrium?

300

Two people of different masses sit on scooters initially at rest. They push on each other and move across the floor in opposite directions. Which has the greater velocity?

The person with less mass

300

In the diagram below, in which position is the total mechanical energy the greatest?

same in all positions because of conservation of energy

300

Two object are sitting on the spinning turntable pictured below. Which has the greater linear (tangential) speed?


The green one.

400

The slope of a distance versus time graph

What is velocity?

400

The ice on a frozen pond begins to crack beneath you. You lie down to save yourself from breaking through.

What is decreasing pressure?

400

Two people of different masses sit on scooters initially at rest. They push on each other and move across the floor in opposite directions. Which has the greater momentum?

Same momentum

400

When you walk versus run up the steps of the Wade Science building from the 1st to the 2nd floor, what does this do to the work you do? to the power required?

Same work, but more power for running

400

Two object are sitting on the spinning turntable pictured below. Which has the greater rotational speed?

They have the same rotational speed.

500


What is free fall (or gravitational acceleration)?

500

An object falls off a cliff and reaches a point where it is in has stopped accelerating (it is in mechanical equilibrium).

What is terminal velocity?

500

Airbags help passengers in car crashes. What do airbags do to the following: time of impact, force of impact, and impulse?

increase time of impact, reduce force of impact, impulse stays the same (same change in momentum)

500

Two identical cars are braking to a stop with the same stopping force. One is traveling twice as fast as the other. The faster car will need ________ the stopping distance.

4 times the stopping distance

500

True of false

An object moving at a constant speed in a circle is not accelerating (has an acceleration = 0 m/s/s) 

False (it has centripetal acceleration, it is channging direction)
