P2- Motion

Question 1

What are the axis on a distance-time graph?

Answer 1

Distance➡️Y-axis.

Time taken➡️X-axis.

Question 2

What is the equation to calculate speed?

Answer 2

Speed (m/s)= Distance (m)/ Time taken (s).

Question 3

Define velocity.

Answer 3

Velocity is speed in a given direction.

Question 4

Define acceleration.

Answer 4

Acceleration is the change of velocity per second.

Question 5

What is the equation to calculate acceleration?

Answer 5

a (m/s²)= (v-u)/t

Question 6

What is the unit for speed and velocity?

Answer 6

m/s

Metres per second.

Question 7

What is the unit for acceleration?

Answer 7

Metres per second squared.

Question 8

If the line on a velocity-time graph is horizontal, what does this mean?

Answer 8

The acceleration is zero.

Question 9

The area under the line on a velocity-time graph tells us….

Answer 9

Distance travelled.

Question 10

The gradient of the line on a velocity-time graph gives…

Answer 10

The acceleration of an object.

Question 11

Define speed.

Answer 11

Distance travelled each second by an object.
