What are the significant similarties and differences between velocity and acceler?

Answer 1

Both Velocity and Acceleration define of an object's rate of motion.

Velocity defines how fast something is moving and, is measured in ft/sec, mi per hr, etc.

Acceleration defines how fast the rate of speed (Velocity) is changing. When you push in the accelerator on a car, you make it go faster.

Acceleration is measured in ft/sec/sec. OR how many ft/sec faster is it moving for every second that the acceleration is applied.

EXAMPLE: The Acceleration due to Gravity is 32 ft/sec/sec.

When you drop something, first released it starts to fall with 0 velocity; after one sec, is it falling at 32 ft/sec; after two seconds is it falling at 64 ft/sec., etc, etc, etc.
