Why would a coffee cup sitting on your car fall off when taking a quick a turn?

inertia makes it want to continue forward

centripetal force makes it want to go backward

centripetal force makes it want to go forward

inertia makes it want to go backward

Its inertia makes it keep on going forward as the car is turning

3 / 10

Acceleration and mass are ______________ related

directly

inversely

4 / 10

Which of Newton's Laws describes an objects resistance to a change in motion or rest?

Newton's First Law

Newton's Second Law

Newton's Third Law

Newtons First Law: Law of inertia

This is about a resistance to change in motion. An object at rest stays at rest and an object in motion stays in motion unless acted upon by an outside force.

5 / 10

You use a spring scale to measure the amount of force required to first start an object moving. You would use this value to determine the coefficient of ___________ friction.

static

kinetic

Coefficient of static friction. The moment the object first starts moving is also almost equivalent to the maximum force provided by friction while the object was at rest or static.

6 / 10

Which number above is where the incline angle would be placed?

7 / 10

What is the final velocity of a ball throw down at 10 m/s after two seconds?

19.8 m/s down

0 m/s

29.6 m/s down

9.6 m/s down

9.6 m/s up

8 / 10

Pick the right equation:

How far did Tony travel when he constantly accelerated from 5 to 15 m/s in 5 seconds?

How far is displacement or x

9 / 10

15 m/s is a _________.

scalar distance

scalar velocity

scalar speed

scalar displacement

vector distance

vector displacement

vector speed

vector velocity

15 m/s is a magnitude only but includes a distance over time so is the scalar speed.

10 / 10

What is your distance after going 10 meters east followed by 3 meter west?

13 meters east

13 meters

7 meters east

7 meters west

7 meters

Distance is a scalar that has no direction. You do nothing with the direction and just add all the individual magnitudes up (10 + 3) here.

You can't put a direction on the final answer since it is a measure of how far you went totally and not a direction.

You should not put a direction on the final answer either since this is not a measure of where you are located but just how far you went in any direction.

If a ball is thrown with a 7 m/s X component of velocity, what is the magnitude of X component velocity if still in the air after 1.3 seconds?

0 m/s

10 m/s

7 m/s

17 m/s

In projectile motion only the Y component of velocity is accelerated. The X component is in constant motion. If it was 7 m/s at the beginning it is still 7 m/s anywhere in the air unchanged.

8 / 20

What will happen to the centripetal force required to keep an object going in a circle if mass, radius, and velocity are all doubled?

It would become ___________ times the original.

half

one

two

four

9 / 20

What will happen to the centripetal force required to keep an object going in a circle if the mass of the object is doubled and the radius of the circle is cut in half?

It would become ___________ times the original.

half

one

two

four

10 / 20

What would happen to the force of gravity if you tripled the distance between the objects?

double the force

triple the force

one third the force

one ninth the force

11 / 20

What is the net force when a 1400 N skydiver encounters 600 N of air resistance?

0 N

800 N down

800 N up

2000 N down

2000 N up

What is the net force when a 1400 N skydiver encounters 600 N of air resistance?

1400 N weight which is a vector directed down and mathematically -1400

600 N air resistance is opposite of motion so up and mathematically is +600

add the vectors together with their signs to get net force

-1400 + 600 = - 800 N or 800 N down

12 / 20

Which of Newton's Laws is most related to all the forces on an object causing the object to accelerate?

First

Second

Third

Newtons First Law: Law of Inertia. An object at rest stays at rest and an object in motion stays in motion unless acted upon by an outside force. (More mass more inertia or resistance to change)

Newtons Second Law: Force causes acceleration (F=ma)

Newtons Third Law: All forces are paired, equal and opposite. When you push on an object with 15 Newtons of force it pushes back on you with 15 Newtons of force.

What is the net force on a 5 kg object that has a force of 20 N applied to the right and 5 newtons applied to the left?

25 N right

15 N left

25 N left

15 N right

Force applied equals the magnitude of force of friction in constant motion. If you find the force of friction (F_f), you know the Force applied (F_A)

What is the correct description of this exact angle?

17 Degrees North of West

17 Degrees West of South

17 Degrees North of East

17 Degrees South of West

17 / 20

What type of motion is seen in this graph?

constant forward velocity

constant backwards velocity

rest

acceleration

deceleration

On a V/T graphs the slope is acceleration. The slope here is flat so no acceleration but it does have a constant velocity of 8 m/s the entire time. Another way to think about it is by what is happening in the graph. The object went 8 m/s and kept going 8 m/s for 30 seconds. Therefore moves 8 meters more every second for 30 seconds.

18 / 20

When a ball is thrown in the air straight up, what is the velocity at the top of its flight?

9.8 m/s up

0 m/s

9.8 m/s down

9.8 m/s/s down

The Y velocity continues to change but is 0 m/s at the top of the flight for an instant.

The acceleration is always 9.8 m/s²down or averaged to 10 m/s²down anywhere in flight but the velocity does change in the Y axis and is 0 m/s at the top

19 / 20

Which variable is bold in the following question:

How fast was Sam traveling if he is traveling at 16 m/s after accelerating at 2 m/s² for 25 meters?

A) v_i

B) v_f

C) a

D) t

E) x

F) v

the unit is (m/s) so its a velocity but there is acceleration so it is not just v

he is traveling at 16 m/s after accelerating at 2 m/s² so we know the final and the question asks for the initial

v_i = ?

20 / 20

What is your average velocity after going 10 meters east followed by 20 meters west in 10 seconds?

1 m/s east

1 m/s west

3 m/s east

3 m/s west

1 m/s

3 m/s

What is your velocity after going 10 meters east followed by 20 meters west in 10 seconds?
Velocity is a vector so direction matters so displacement divided by time. Make the directions into signs.
10 m east is +10
20 m west is -20
now calculate displacement and divide that by time ((+10)+(-20))/10
-10/10 = -1 m/s
turn the negative back into a direction 1 m/s west
