If you're moving faster now than you were a second ago, your acceleration is positive.
If you're moving slower now than you were a second ago, your acceleration is negative.
it changes the speed
decelration
accelaration?
g is gravitational accelaration
Because the earth is much more heavier than the moon.
Acceleration is any change in velocity.
9.8m/s^2
It's a vector one.
Acceleration is the rate at which an object's velocity changes over time. It can be a change in speed, direction, or both. A positive acceleration indicates speeding up, while negative acceleration (deceleration) indicates slowing down.
accelaration.
When an object is not accelerating at all. It has constant velocity.
