Acceleration is the time rate of change of velocity. If velocity is constant, then. acceleration is zero. Note: 100 km per h for 10 seconds is a constant speed, but not necessarily a constant. velocity, since we're told nothing about the direction.
There are three basic ways that we control the motion of our cars. They are (1) speed, (2) braking, and (3) steering. Each of these functions is affected by the laws of gravity, centrifugal force, inertia, kinetic energy, and friction. ENERGY=SPEED. When you accelerate your car, you are increasing the car's energy. Keep in mind, the faster the car is moving, the longer it will take for the vehicle to stop.
