Acceleration is a change in velocity over time. When you accelerate in a car, you increase the speed in which you are going. Similarly, when slowing down your car by pressing the brakes, you are decelerating. This occurs when your final speed is lower than your initial speed.
A simple way to calculate average acceleration within a time period is to use this equation:
[Acceleration] = ([Final Velocity] - [Initial Velocity]) / [Time of Acceleration]
If a person was to be traveling 5 meters per second, and then they accelerated to 10 meters per second in a time period of 5 seconds, their acceleration would be:
A = (10m/s - 5m/s) / 5s = 1m/s2
This acceleration is equivalent to going from a jog to an all-out sprint in five seconds.
Acceleration is any change in velocity.
accelaration.
it changes the speed
decelration
accelaration?
g is gravitational accelaration
Because the earth is much more heavier than the moon.
9.8m/s^2
It's a vector one.
When an object is not accelerating at all. It has constant velocity.
5.3sec
It should be, but many people do not treat it as such.
