Q

Typical speed of a plane

A

250 m/s

19
Q

A car is travelling along a road and collides with a tree, estimate the deceleration

A

-25 m/s

20
Q

What is uniform acceleration

A

Constant acceleration.

21
Q

Equation for uniform acceleration

A

V^2 - u^2 =2as
V = final velocitt
U = initial velocity
A = acceleration
S = distance

22
Q

Example of difference between speed and velocity:

A

A car travelling north at 30m/s has the same speed as a car travelling south at 30m/s, but their velocities arent the same due to the different directions

23
Q

What can measure velocity changes?

A

A motion sensor linked to a computer

24
Q

Gradient of a line =

A

Height of triangle/base of triangle
