10 questions from our bank of first semester material

1 / 10

What is the unit for momentum?

m/s

kg∙m/s

N∙m/s

2 / 10

What is the maximum magnitude of vector A and B in any arrangement?

B + A

B - A

Greater than B but less than B + A

Magnitude includes the number and a unit. Since no numbers are involved the length of the arrow represents the magnitude. The directions are pointing the same way but the lengths are different.

Maximum is B + A or A + B

0 W

8.3 W

50 W

When a bug hits your windshield. Which of the following are true?

The bug applies an equal of force to your windshield as your windshield to the bug

The windshield applies more force to the bug than the bug to the windshield

The bug applies more force to the windshield than the windshield to the bug

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. The forces are equal.

5 / 10

Force and acceleration are ______________ related

directly

inversely

6 / 10

Which is almost always greater

kinetic friction

static friction

rolling friction

When an object is at rest (static) the surfaces between objects are settled and closer together. With surfaces closer together there is more interaction and therefore more static friction friction than kinetic.

7 / 10

Which 2D Vector drawing correctly describes the overall and components of South of East

8 / 10

What type of motion is seen in this graph?

constant forward velocity

constant backwards velocity

rest

acceleration

deceleration

A straight line means something is constant. A straight sloped up line on a position time graph meant the position is moving at a constant rate or constant velocity.

9 / 10

10 / 10

Pick the right equation and solve the problem:

What is the acceleration of a person that accelerates from 10 m/s to 30 m/s in 5 seconds?

2 m/s/s

8.7 m/s/s

1 / 20

What type of collision is the following?

A 5 kg bowling ball traveling 2 m/s right hits a 4 kg bowling ball at rest. After the collision the 4 kg bowling ball is traveling right at 2.5 m/s right.

elastic collision

inelastic collision

neither

In an elastic collision objects maintain their shape and travel independently afterwards

In an inelastic collision at least one object changes its shape and heat is lost

How much force is required to stop Big Mac a 135 kg football player running at 6.0 m/s in 0.050 seconds?

16200 N

8734 N

14200 N

452 N

A drone looses battery power from a height of 72 meter while flying horizontally at 12 m/s. How far from the ground below will it land forward? (neglecting air resistance)

46 m

92.1 m

60.6 m

23.5 m

4 / 20

A ball is thrown horizontally at 20 meters per second and takes 1.3 second to hit the ground. What happens to the time the object takes to fall if thrown much faster at 45 m/s?

It would take more than 1.3 seconds to hit the ground

It would take less than 1.3 seconds to hit the ground

It would take 1.3 seconds to hit the ground

The X and Y motion are independent. No matter how fast forward something is thrown, in the Y axis the object acts like it's falling. On earth an object falling from the same height would take the same time to hit the ground no matter how fast forward it is thrown or if it is just dropped. (ignoring air resistance)

5 / 20

20 degrees north is a

scalar

vector

A scalar has a magnitude only which includes a number and unit (15 meters)

A vector has a magnitude and a direction (15 meters north)

6 / 20

50 meters is a

magnitude

direction

both magnitude and direction

A magnitude includes a number and a unit

15 meters (15 is the number) (meters is the unit)

A 460 N box is hoisted above a truck by John who applies 60 N of force. What is the actual mechanical advantage of the pulley system?

0.13

7.67

27600

2760

8 / 20

What is the power output when it takes a force of 50N forward is applied to move a box 6 meters in the same direction in 6 seconds?

0 W

8.3 W

50 W

300 W

9 / 20

Which graph correctly shows how distance relates to force using the Law of Universal Gravitation?

Distance is in the denominator and squared in the universal gravitation equation below. There is a inverse squared relation. Force decreases not proportionately more early since the d is squared. If you double distance the force goes down to 1/4.

10 / 20

What is the spring constant of a spring displaced 0.1 meters when 400 N of force is applied?

40 N/m

4000 N/m

384 N/m

10 N/m

11 / 20

What happens to the magnitude of force required to stretch a spring 0.1 m when the spring constant increases?

force must increase

force must decrease

force stays the same

12 / 20

What is the tension in a rope when you apply a force of 100 N to pull an object forward in constant motion.

0 N

100 N backward

10 N backward

100 N forward

10 N forward

13 / 20

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

5 m/s/s right

3 m/s/s left

5 m/s/s left

3 m/s/s right

14 / 20

Which is the term for the molecules that make up an object.

mass

weight

Matter is composed of the atoms/molecules that make up an object

15 / 20

Which changes depending on your location?

mass

weight

Mass (kg) never changes because it is a measure of the matter that you are composed of. You are the same matter on earth or on the moon.

Weight (F_w) changes when g changes. g changes depending on your altitude on earth, in space, or on another planet (it is not always 9.8 m/s²which is why many classes use a more rounded 10 m/s²instead.

(F_w = mg)

16 / 20

What happens to the downhill force as the angle of incline increases?

Increases

Decreases

Larger incline means more force downhill

17 / 20

One ball is thrown up and another is dropped. Which ball will have a greater acceleration after 2 seconds?

the ball thrown up

the ball dropped

both will be the same

The acceleration is always 9.8 m/s²down or averaged to 10 m/s²down

It does not matter what happened to get it there. Thrown up, dropped, or thrown down they all have different velocities but those velocities change by 9.8 m/s²down

18 / 20

Pick the right equation and solve the problem:

A duck flew 500 meters in 40 seconds. How fast was the duck flying?

0.08 m/s

12.5 m/s

3.7 m/s

20000. m

19 / 20

What it the direction of 15 meters north?

15 meters

15 meters north

meters

north

north is the direction the 15 m is pointing

20 / 20

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.
