Velocity, Distance, Time, and Acceleration (70 & 71)

Question 1

What is the difference between Speed and Velocity?

Answer 1

Speed only has a magnitude (or amount) while Velocity has a magnitude and a direction.

Question 2

What is the formula for Speed?

Answer 2

Speed=Distance/Time

Question 3

How do you find the Speed on a Distance-Time graph?

Answer 3

You find the gradient of the line.

Question 4

How do you find the gradient of the line?

Answer 4

Divide the change in the y-axis by the change in the x-axis.

Question 5

What is Acceleration?

Answer 5

Acceleration is the rate at which the Velocity is changing.

Question 6

How do you find the Acceleration?

Answer 6

Find the change in Velocity and then divide it by the Time taken.

Question 7

What is the formula for Acceleration?

Answer 7

a=(v-u)/t

Question 8

What is the unit for Acceleration?

Answer 8

m/s²

Question 9

How do you find the Acceleration on a Velocity-Time Graph?

Answer 9

You find the gradient of the line.

Question 10

How do you find the Distance travelled on a Velocity-Time graph?

Answer 10

You find the area underneath the line.
