what is physics
... When the velocity of an object changes, the object accelerates. Acceleration is the rate of change in velocity: a = v / t (Acceleration [m/s2] = Velocity [m/s] / Time [s]) Example 2. A car goes from rest to 20 m/s in 6 s. What is its acceleration? 2A. (1) a = v / t (2) a = 20 m/s / 6 s (3) a = 3 ...

Bigger truck so 2x the energy But ½ the velocity so ¼ the energy So truck has ½ the KE of the car 42. What does this say about the braking force needed to stop a car as its speed increases? ...
