10 - 1D Motion Questions

1 / 10

What does the slope of a velocity time graph determine?

displacement

velocity

acceleration

Acceleration which is the rate at which the (Y axis) velocity on a V/T graph is changing.

In the graph provided the object is going 8 meters every seconds (so is moving) but no slope or acceleration.

2 / 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.

3 / 10

One ball is thrown down at 5 m/s and another is thrown down at 10 m/s at the same time. How will the distance between them change as they fall.

the 10 m/s second ball will keep getting further away

the 5 m/s ball will be catching up with the 10 m/s ball

they will maintain the same distance apart during the fall

The ball thrown down will always be traveling faster as they both change by 9.8 m/s²down

Since traveling faster the ball thrown downwards will always be getting further ahead

An acceleration of 9.8 m/s²down means a rock thrown

5 m/s down will be going 14.8 m/s a second later (going 14.8 meters in a second - if that rate was maintained)
10 m/s down will be going 19.8 m/s a second later (going 19.8 meters in a second - if that rate was maintained)

The one going faster will always be faster and getting further away

4 / 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 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 m west becomes (-20)

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

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.

2 / 20

What is the displacement between 5 and 15 seconds

0 m forward

8 m forward

40 m forward

80 m forward

3 / 20

What type of motion is seen in this graph?

constant forward velocity

constant backwards velocity

rest

acceleration

deceleration

Went from 16 meters to 8 meters (backwards 8 meters) in 30 seconds. The slope on a position or displacement time graph is equal to velocity

Constant velocity backwards

4 / 20

What type of motion is seen in this graph?

constant forward velocity

constant backwards velocity

rest

acceleration

deceleration

5 / 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.

6 / 20

One ball is thrown down at 5 m/s and another is thrown down at 10 m/s at the same time. How will the distance between them change as they fall.

the 10 m/s second ball will keep getting further away

the 5 m/s ball will be catching up with the 10 m/s ball

they will maintain the same distance apart during the fall

The ball thrown down will always be traveling faster as they both change by 9.8 m/s²down

Since traveling faster the ball thrown downwards will always be getting further ahead

An acceleration of 9.8 m/s²down means a rock thrown

5 m/s down will be going 14.8 m/s a second later (going 14.8 meters in a second - if that rate was maintained)
10 m/s down will be going 19.8 m/s a second later (going 19.8 meters in a second - if that rate was maintained)

The one going faster will always be faster and getting further away

7 / 20

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

8 / 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

9 / 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

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
