If the man and car have a mass of 3 Kg, what is the acceleration?

1 m/s^2

20

If the plane weighs 35 Kg, what is it's acceleration?

20 m/s^2

25

What's the difference between speed and velocity?

Velocity is speed with direction

5

If a car is traveling 234 miles per hour east, which of these statements is true?

The speed is 3.9 mi/s east

The acceleration is 3.9 mi/s^2

The acceleration is 234 mi/s^2

The velocity is 3.9 mi/s east

25

When mass is held constant, as force increases, what happens to the acceleration?

Increases

20

Why does the water keep moving when the man and cup are stopped due to tripping?

Inertia (Objects in motion stay in motion, Newton's 1st Law)

10

Which of Newton's Laws is best shown through swimming?

3rd

10

Which row(s) will have the greatest acceleration?

2 and 4

10

If a car drives 50 meters in 30 minutes, what was it's speed in meters per hour?

100 m/h

25

How much force would it take to swing a 2kg bat at 5 m/s^2?

10 N

20

The diagram shows two forces acting on a moving train. Make a true statement about what will happen when the two forces are applied to the train

The train will accelerate because of unbalanced forces.

The train will continue to move at a constant speed

The train will slow down because the forces are balanced.

The train will come to a complete stop

20

Which option correctly pairs the motion with the units?

S=m/s^2 East, V=m/s East, A=m/s

S=m, V=m/s , A=m/s East

S=m/s, V=m/s East, A=m/s^2 East

S=m/s East, V=m/s, A=m/s^2 East

25

A car travels 30m in 60s. If it continues at this speed, how far will it travel in 100s?

50 m

25

What's the magnitude of the net force?

50N to the left
