100
The unit for force
What is a Newton
100

The unit for velocity

Meters per second

100
The difference between weight and mass
What is Weight is how gravity acts on an object, mass is what makes up the object.
100

What is the acceleration formula?

a=(Vf-Vi)/t

100
the acceleration due to gravity
What is 9.8 m/s2
200

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

0 m/s

200

A hammer and a feather are dropped at the same time on the moon. They both reach the ground at the same time. Why?

There is no air, so all objects will fall at the same rate

200
the forces acting on a ball thrown into the air?
What is air resistance and gravity
200

This is the formula to calculate Speed

What is distance ÷ time?

200

What is the definition of static equilibrium

An object at rest

300

What is "g"?

Acceleration due to gravity in formulas

300
If a tennis ball was thrown off the top of NGC and hit the ground in 3.2 seconds, How fast will it be traveling when it hits the ground?

31.4 m/s

300

What is the formula for solving the downward force problem in an elevator?

F = mg - ma

300

The difference between Speed and velocity

Speed refers to how fast an object is moving, only considering the magnitude of its motion, while velocity indicates both the speed and the direction of an object's movement

300

In acceleration formula, what does Vi stand for?

Initial Velocity

400

A 5 kg block is pulled on a frictionless horizontal plane at 5 m/s2. Find the tension in the string holding it in place.

5 * 9.8 + 5 * 5 = 74N

400

The three symbols for the speed formula.

What are "s," "t," and "d"?

400

If a force of 50 N is applied to a block of mass 10 kg and does not move, what is the coefficient of friction for the block and table?

(10 )(9.8) = 98N = 50/98 =.51u

400

Two masses, m1 = 2  kg and m2 = 3 kg, are connected by a light string over a frictionless pulley. Find the acceleration of the system.

((3 - 2) ÷ ( 2 + 3)) * 9.8 = 1.96

400

What is the formula used to solve tension on an inclined plane?

What is 

T = m*g *sin(θ)

500

The distance a car traveled if it drove at 40 m/s for 30 minutes (Convert to km) 

1minute = 60 secs

1km = 1000m

What is 72 km?

D = v*t = 40 m/s * 1800 s

D= 72,000 m = 72 km

500

Otis has a mass of 45 kg; what is the scale reading when Otis is traveling upward at a constant velocity of 2 m/s on an elevator?

(45 )(9.81 ) = 441.45 N

500

Does your weight increase or decrease when traveling upward on an elevator?

What is Increases
