shows speed
velocity time graphs gradient
shows acceleration
momentum
depends on an objects mass and velocity
total momentum before collision
equals total momentum after collision
impulse
change in momentum
stopping distance equation
thinking distance + braking distance
stopping distance
the total distance travelled during the time it takes for a car to stop in response to an emergency
thinking distance
