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.
A force (you and your friends); acting on a mass (pushing a car); will accelerate the car (the rate at which the velocity increases, ignoring other forces) by the equation; Force (newtons: N) = mass (kilograms: kg) * acceleration (metes per seconds squared: m/s^2)
