Acceleration is any change in velocity.
accelaration.
it changes the speed
decelration
Because the earth is much more heavier than the moon.
accelaration?
g is gravitational accelaration
9.8m/s^2
It's a vector one.
force=mass*accelaration force/mass=accelaration 4/2=2m/s2
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.
