Speed is the rate of change of distance over time. Acceleration is the rate of change of speed over time. Acceleration is a change in speed or direction of motion.

Speed and Acceleration

Speed: The rate of change of an object's position, usually measured in meters per second (m/s) Acceleration: The rate of change of velocity, usually measured in meters per second squared (m/s2) Force: The push or pull on an object, usually measured in Newtons (N)

Faster objects experience time at a slower rate. This phenomenon is known as time dilation and was first predicted by Albert Einstein's Theory of Relativity. The world record for acceleration in a motor vehicle was set in 1997, when the Thrust SSC was the first car to break the sound barrier, reaching a speed of 763 mph. The speed of light, or 300,000,000 meters per second, is the fastest speed at which energy or information can travel.

Question: A car is driving down the highway at a constant speed. How can you explain why its acceleration is zero? Clues: â€˘ Acceleration is the rate of change of velocity. â€˘ Velocity is a vector quantity which has both magnitude and direction. â€˘ If the magnitude of the velocity does not change, then the acceleration is zero. In pairs: Select and solve one of the tasks: A. Draw a diagram to explain why the car's acceleration is zero. B. Explain the concept of acceleration to your partner using your diagram.
