A car is easier to push than a bus. This is an example of which of Newton's Laws?

2nd Law
100

This is a push or pull.

Force

100

This is the force that pulls you toward the center of the Earth.

Gravity

100

This is the distance from crest to crest or trough to trough.

Wavelength

100
Differentiate between red and blue shift.

Red = objects moving away

Blue = objects moving toward

200

You are thrown off the front of a 4 wheeler when it runs into a fence. This is an example of which law of motion?

1st Law

200

This is a resistance to change. (1st Law)

Inertia

200

If 2 magnets are attracted to one another, which poles have to be facing one another?

North & South

200

This is the number of waves produced in a certain amount of time. 

Frequency

200

Differentiate between spring and neap tides.

Spring = straight

Neap = 90 degrees

300

You let the air out of a balloon- the air goes one way and the balloon goes the opposite direction. This is an example of which law of motion?

3rd Law

300

This is a force of resistance between 2 objects that are touching.

Friction

300

What creates more power in an electromagnet?

More coils

300

This is the measurement from the top of the wave to the middle of the wave. 

Amplitude

300

Which elements are fused during the Main Sequence Stage of a Star?

Hydrogen & Helium

400

A baseball hit with a wooden bat goes farther than a baseball hit with a plastic bat. This is an example of which law of motion?

2nd Law

400

If you push on a wall with 20N of force and there is no movement, what kind of forces are at play?

Balanced Forces

400

What are the 4 non-contact forces?

Gravity, Electricity, Magnetism, Nuclear

400
Differentiate between electromagnetic and mechanical waves.

EM = no medium required

M = medium required

400

What 2 factors affect the force of gravity?

mass and distance

500

A kickball continues to roll until it hits the fence. This is an example of which law of motion?

1st Law

500

If you apply 40 N of force to desk, but the desk only applies 30 N back, what kind of forces are applied?

Unbalanced

500

Name the parts of an electromagnet. (3)

Coil (Solenoid)

Iron Core (Nail)

Power Source (Battery)

500

Differentiate between transverse and longitudinal waves.

Transverse = perpendicular

Longitudinal = parallel

500

Draw the life cycle of a medium sized star. 

Nebula, Protostar, Main Sequence, Red Giant, White Dwarf
