100
It's a speed in a particular direction.
What is velocity
100
It's the term for a change in velocity, shown in the equation here:

What is acceleration?
100
It's the term for Newton's First Law, which says objects tend to keep doing what they're doing.
What is inertia
100
It's the mass of a 100 kg man if he travels to the moon, where the gravity is 1/6 as much as the earth.
What is 100 kg.
100
It's the part of the wave labeled 'A' in the diagram.

What is crest?
200
It's the speed traveled by a car that goes 25 km in 5 hours. Don't forget units!
What is 5 km/h
200
It's the acceleration of a car that speeds up from 0 m/s to 6 m/s in 2.0 seconds.
What is 3 m/s/s
200
It's the equation that represents Newton's Second Law, describing how forces and mass affect the acceleration of an object.
What is a = F / m

200
It's the primary force between protons and neutrons in an atom.

Choose from: gravitational, electrical, magnetic, nuclear
What is electrical
200
It's the property of the wave labeled 'B' in the diagram.

What is wavelength?
300
The equation for it is shown here:

What is velocity or speed?
300
It's the speed of an object, starting from rest, that accelerates at 5 m/s/s, after 1.0 second.
What is 5.0 m/s?
300
It's the reaction force, if a bulldozer pushes a tree with 1200 N to the north.
The tree pushes on the bulldozer, 1200 N to the south.
300
It's the primary force between the sun and planets in our solar system.

Choose from: gravitational, electrical, magnetic, nuclear
What is gravitational
300
It's the property of the wave labeled 'C' in the diagram.

What is amplitude
400
It's the speed of a snail that travels 0.5 cm in 2 minutes.
What is 0.25 cm/minute
400
It's the speed of an object, starting from rest, that accelerates at 5 m/s/s, after 2.0 seconds.
What is 10 m/s
400
It's the acceleration of the object below:

What is 0 m/s/s
400
It's the weight of a 600 N person who travels to the moon, where the gravity is 1/6 of the gravity on the earth.
What is 100 N
400
It's the part of the wave labeled 'D' in the diagram.

What is a trough?
500
It's the speed of the object between 40 and 70 seconds on the graph shown:

What is 0 m/s
500
Was the object in the graph accelerating? Why or why not?

YES! It's position vs. time graph is not linear -- the slope (speed) changes.
500
How would doubling the mass affect the acceleration of an object?

It would cut the acceleration in half.
500
This, the measure of the amount of matter in an object, does not change depending on gravity.
What is mass?
500
