Sharis decides to be brave and go skydiving. If she accelerates at 9.81 m/s2 (m/s2 = m/s/s) for 4.9 s, what would her speed be at that time?
48.1 m/s
0.6 m/s
0.0015 m/s
7.1 m/s
Select the description of motion from A - B.
Slowing down away from the origin
Speeding up away from the origin
Constant velocity away from the origin
Constant velocity towards the origin
Part A of the graph is from 0s to 25s. Which of these statements is true about Part A?
The object is at rest.
The object is accelerating (its velocity is increasing)
The object is decelerating (its velocity is decreasing)
The object is moving at a constant velocity.
Part C of the graph is from 35s to 55s. Which of these statements is true about Part C?
The object is at rest.
The object is accelerating (its velocity is increasing)
The object is decelerating (its velocity is decreasing)
The object is moving at a constant velocity.
What does a flat (horizontal) line on a velocity-time graph mean?
[Example section B on this graph]
The object is not moving.
The object is moving, but at a constant velocity.
The object is accelerating, and its acceleration is positive.
The object is accelerating, and its acceleration is negative.
What does a line with a positive slope mean on a velocity-time graph?
[Example sections A, E on this graph]
The object is not moving.
The object is moving, but at a constant velocity.
The object is accelerating, and its acceleration is positive.
The object is accelerating, and its acceleration is negative.
What does a line with a negative slope mean on a velocity-time graph?
[Example sections C, D on this graph]
The object is not moving.
The object is moving, but at a constant velocity.
The object is accelerating, and its acceleration is positive.
The object is accelerating, and its acceleration is negative.
You can calculate the slope of a velocity-time graph.
If you calculate the slope of the graph between two points, what would that tell you?
The velocity of the object.
The distance travelled by the object.
The acceleration of the object.
The mass of the object
During section A of the graph (between 0s and 25s), the object is accelerating.
Change in velocity in this time = 3 - 0 = 3m/s
Time taken = 25 - 0 = 25s
What is its acceleration?
Acceleration = Change in velocity x time = 3 x 25 = 75m/s2
Acceleration = Change in velocity / time = 3/25 = 0.12m/s2
A roller coasters accelerates from an initial speed of 6.0 m/s to a final speed of 70 m/s over 4 seconds. What's the acceleration?
24 m/s2
18 m/s2
16 m/s2
16 m/s
The picture of the distance vs. time graph shows an object that is...
accelerating/speeding up
moving at a constant speed
not moving
accelerating/slowing down.
