10 - 1D Motion Questions

1 / 10

What is the acceleration of this object over the 30 second time period?

0.2 m/s/s

0.4 m/s/s

2.5 m/s/s

360 m/s/s

Slope of a velocity time graph is acceleration. Either find the slope or turn it into an equations picking givens off the graph (either way you are doing the same thing)

2 / 10

What does the slope of a position time graph determine?

displacement

velocity

acceleration

The rate at which the position or displacement is changing. This object goes from 16 meters to 8 meters or is going backwards for the 30 seconds. The straight line means the type of motion is constant.

Constant backward velocity

3 / 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.

4 / 10

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.

5 / 10

One ball is thrown up and another is dropped. Which ball will have a greater downward velocity 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.

The ball dropped would have a head start and always be traveling faster downwards

6 / 10

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

9.8 m/s/s up

0 m/s

0 m/s/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

7 / 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

8 / 10

A change in displacement over time is ______________.

displacement

velocity

acceleration

distance

v = (Δx)/t

The change in displacement over time is the definition of velocity. See the equation above

9 / 10

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 for acceleration is m/s²

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.

20 - 1D Motion Questions

1 / 20

A 0.5 kg rock and a 150 kg boulder were dropped from a cliff 65 meters high. Which one would hit the ground first ignoring air resistance?

0.5 kg rock

150 kilogram boulder

both at the same time

Neglecting air resistance. Any mass would take the same time to hit the ground no matter how massive or minute. Many times a question may say in a vacuum which means there is no air resistance since air particles are sucked out removed from a vacuum.

What is the acceleration of this object over the 30 second time period?

0.2 m/s/s

0.4 m/s/s

2.5 m/s/s

360 m/s/s

Slope of a velocity time graph is acceleration. Either find the slope or turn it into an equations picking givens off the graph (either way you are doing the same thing)

0.18 m/s

0.27 m/s

4 / 20

What does the slope of a position time graph determine?

displacement

acceleration

Constant backward velocity

5 / 20

What type of motion is seen in this graph?

constant forward velocity

constant backwards velocity

rest

acceleration

deceleration

Was moving at a constant rate of -4 m/s velocity for 30 seconds or had a constant backward velocity of 4 meters per second.

Slope on a V/T graph is equal to acceleration. There was no acceleration because the slope was flat, but there was a velocity the whole time.

6 / 20

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.

7 / 20

What type of motion is seen in this graph?

constant forward velocity

constant backwards velocity

rest

acceleration

deceleration

On a P/T graphs the slope is velocity. The slope here is flat so no velocity. Another way to think about it is by what is happening in the graph. The object went from 16 meters to 16 meters in 30 seconds. Therefore is in the same place and did not move.

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

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

Displacement is vector and a measure of how far you are from start to finish. Take into account the direction.

10 m east becomes (+10)

20 m west becomes (-20)

add them together including the sign ((+10) + (-20))

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

20 / 20

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.
