1
Q
what is the calculation for speed
A
speed = distance/time
2
Q
how can you calculate the speed in a distance-time graph
A
find the gradient
3
Q
what is acceleration
A
acceleration is a change of speed
4
Q
how can you calculate acceleration
A
acceleration= change in speed/ time taken
a= final speed-starting speed /time
5
Q
how do you know it is a steady speed in a speed- time graph
A
it is a straight horizontal line
6
Q
how much is a newton is kg
A
1kg
7
Q
how do you calculate density
A
p=m/v
8
Q
how do you calculate pressure
A
pressure= force/area
