Motion

Question 1

What is the equation for speed?

Answer 1

Speed(m/s) = Distance (m) % time (s)

Question 2

How do you work out the distance travelled in a distance time graph?

Answer 2

You work out the area of the space underneath the lines

Question 3

What is the equation for acceleration?

Answer 3

Axt = V-u

Acceleration (m/s2) = velocity change (final velocity - initial velocity) % time taken

Question 4

What is deceleration?

Answer 4

The negative of acceleration

Question 5

What is the SUVAT equation to work out acceleration?

Answer 5

2A x s = V2 - u2
2x acceleration x displacement = final velocity (squared) - initial velocity (sqaured)
