100

The force used to accelerate a 5 kg mass at 5 m/s/s.

What is 30 N?

5 x 5 = 25 -> Sig Figs -> 30N

100

You must push a big kid harder than you do a small kid to get them to swing at the same tempo on the swings.

What is Newton's 2nd Law?

100

This measurement uses the units: kilograms

What is mass?

100

This is the resistive force between surfaces.

What is friction?

100

The direction of acceleration when a rightward moving car is slowing down.

What is left?

200

The mass that gets accelerated at 2.0 m/s/s from a 12N force.

What is 6.0 kg?

12/2.0 = 6.0

200

Your tires push the road backwards. The road pushes the car forwards.

What is Newton's 3rd Law?

200

This measurement uses the units: Newtons

What is force?

200

This force is dependent upon surface area and shape. We are often times told to neglect it.

What is air resistance?

200

The direction of acceleration when a leftward moving car is speeding up.

What is left?

300

The acceleration given to a 3.0 kg object when pushed with a 15 N force.

What is 5.0 m/s/s?

15 / 3.0 = 5.0

300

Objects will maintain their current state of motion unless acted upon by an outside unbalanced force.

What is Newton's 1st Law?

300

This measurement uses the units: m/s/s or m/s2

What is acceleration?

300

This is the type of force that is felt by a wire with a mass hanging from it.

What is the force of Tension?

300

An object will not accelerate if the net force is this.

What is zero? or What is forces are balanced?

400

The number of sig figs in 201,000

What is 3?

400

AKA the Law of Inertia

What is Newton's 1st Law?

400

This variable is represented by the letter little "g"

What is Gravity?

400

This is the type of force that pushes up on a boat and keeps it floating.

What is the force of buoyancy?

400

The direction of a net force is the direction of this.

What is the acceleration?
500

The number of sig figs in 0.0050

What is 2?

500

This law explains why rockets work even in outer space.

What is Newton's 3rd Law?

500
This measurement is sometimes called weight when the acceleration is due to gravity

What is force?

500

This is the force that always works perpendicular to the surface.

What is the Normal Force?

500

This is the acceleration due to gravity on Earth to 3 Sig Figs.
