If an object is at rest, what is its velocity?

0 m/s

100

The Unit for Distance

M

Meters

100

Newtons First Law States

An object in motion will stay in motion, an object at rest will stay at rest unless acted upon by an outside force

100

This is the formula to calculate Speed

What is distance ÷ time?

100

What happens when two negatively charged electrons come near each other?

They repel each other

200

What is "g"?

Acceleration due to gravity

9.81

200

The unit for velocity

m/s

Meters Per Second

200

Newton's Third Law

Every action or Force has an equal and opposite reaction

200

What is the acceleration formula?

a=V/t

200

Give one difference between convection and conduction

  • Conduction: Heat transfers through direct contact between particles
  • Convection: Heat transfers through the movement of a fluid (liquid or gas) 
300

If you throw a ball straight up, what is its velocity at the highest height?

0 m/s
300

The unit for acceleration

m/s2

Meters Per Second Squared (to the second power)

300

Newton's Second Law 

F=M*A

Force is equal to mass times the acceleration

300

The difference between Scalar and vector.

Scalar only indicates magnitude while vector indicates magnitude and direction.

Why do lights in parallel circuits stay on when one bulb goes out?

Parallel circuits provide another path/wire for the electricity to flow in one bulb goes out

400
Velocity and Speed are similar but a key difference is...

Velocity is Vector while Speed is Scalar

Velocity can be negative, Speed cannot


400

The Unit for Force

N

Newtons

400

A 10 kg object experiences a net force of 50 N. What is its acceleration?

5 m/s2

400

A bullet and a marker that rolled off a desk will fall at the same speed. Why?

all objects accelerate at the same rate (about 9.8 m/s²) near Earth

400

A spring stretches 0.2 m when a force of 10 N is applied. What is the spring constant (k)?

50 N/m

500

The distance a car travelled if it drove at 40 m/s for 300 seconds

D= v*t

D = v*t = 40 m/s * 300 s

D= 21,000 m

500

One Thousandth of a meter

mm

Milimeter

500

What is inertia?

the natural tendency of an object to resist changes in its state of motion, meaning an object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by an external force.

Tyler runs the basketball court 5 times (from one side back to the other 5 times). Ending in his original starting place. What is Tyler's displacement at the end of his run?

0 meters. He ended where he started
