The four fundamental forces of nature are:

• Electromagnetism, Gravity, Strong Nuclear, Weak Nuclear
• Gravity, Strong Nuclear, Weak Nuclear, Medium Nuclear
• Normal Force, Force due to gravity, Magnetism, Nuclear
• Nuclear, Electricity, Gravity, Atomic

A natural resource that cannot be remade or re-grown at a scale comparable to its consumption.

• Nonrenewable
• Renewable
• Slownewable
• Fastnewable

Natural resources that can be replenished in a short period of time

• Nonrenewable
• Renewable
• Slownewable
• Fastnewable

Gravity is due to

• the pull between Earth and the moon.
• the pull between the Sun and Earth.
• the pull between any objects with mass.
• the pull between atomic nuclei.

The strongest of the four fundamental forces is

• Gravity
• Electromagnetism
• Strong Nuclear
• Weak Nuclear

What is distance?

• How fast you travel
• study of motion
• How long you take
• How far you have traveled

How far away is the dog from the house?

• 90m
• 60m
• 40m
• 50m

What is Mass?

• a push or a pull
• a force that opposes motion between 2 objects that are touching
• tendency of all objects to stay at rest or in motion
• the amount of matter an object is made of

What is Newton 2nd Law of Motion?

• F=ma
• For every force, there is an equal and opposite force
• An object at rest remains at rest and an object in motion remains in motion

What does the F mean in the equation F=ma?

• acceleration
• mass
• Force
