Effect of higher speed on stopping distance
Effect of higher speed on stopping distance
Stopping distance increases
How thinking & braking distance increase with speed
How thinking & braking distance increase with speed
At different rates
How thinking distance changes with speed
How thinking distance changes with speed
Increases at same rate as speed
Why thinking distance increases with speed
Why thinking distance increases with speed
Reaction time constant; more distance covered at higher speed
Why braking distance increases with speed
Why braking distance increases with speed
More speed means more kinetic energy to transfer
Kinetic energy equation
Kinetic energy equation
How kinetic energy changes as speed increases
How kinetic energy changes as speed increases
Increases at a higher rate
Why more distance needed to stop at higher speed
Why more distance needed to stop at higher speed
More work needed to transfer KE (, force constant)
