Forces on Cars.


When cars first set off they have much more force accelerating them than resistance slowing them down. As the speed increases the resistance builds up.





This gradually reduces the acceleration.

Forces on Cars.


When the resistance force is equal to the accelerating force it won’t be able to accelerate anymore and it will have reached its maximum speed or Terminal Velocity.
