What is the formula to work out the net force
ma
What is the formula to work out acceleration
Change in velocity / change in time
What unit of measurement do you measure forces in
Newtons
How do you work out the net force
What is the difference between the 2 numbers
What does it mean if the net force is 0N
It is balanced
What does it mean if the net force is greater than 0N
It is unbalanced
V =
Change in distance / change in time
What does a slope mean on a graph
Accelerating
What does a straight diagonal line mean on a graph
It is moving at a constant speed
What does it mean if there is a straight line on a graph
It is stationary
What is the formula for gravity
9.8ms-2
What is weight
The gravity on mass (N)
What is mass
How much matter there is (kg)
What is the formula to work out weight force
mass x gravity

Support
What is the arrow called facing the direction it is moving
Push
What is the arrow called facing the direction the opposite way it is moving
Friction
What is the arrow called facing down
Weight
What unit of measurement is velocity measured in
V = ms-1
What unit of measurement is distance measured in
d = m / km
What unit of measurement is time measured in
t = s / hr
