Why do raindrops fall with a constant speed?
Gravity pushes the rain down at a constant speed. However something simple like wind can affect the rate it falls.
Is the speed of gravity a constant?
It is believed that any change in the gravitational field (caused by movement of masses) would propagate at the speed of light. And yes, that would be a constant.
What is the constant speed of an object reached when the force of gravity is balanced by air resistance?
Terminal Velocity
What is the speed of light in zero gravity?
Gravity does not effect speed of light ,so velocity is constant. Even if it effect the effect is negligible. So in short answer is 3*108ms-1 -Thunder
Why does the speed of a ball thrown against gravity decrease?
Because gravity exerts a constant force on it in the opposite direction. Just as you do to stop a shopping cart that's rolling away.

What quantities are changing when you are running on a circular track at a constant speed?
gravity, in the form of centrifugal force

What forces act on a moon which is moving around a planet at the constant speed?
Gravity, in balance with centripetal reaction force.
When is acceleration constant?
We have constant acceleration all the time. Its called gravity. Gravitational acceleration is 9.8... m/s^2
Do asteroids have constant speed?
Asteroids have a constant speed in a vacuum if there isnt anything else affecting it such as gravity or by colliding with other things. If it was to be in the earths atmosphere then the air would cause a resistance and slow it down :) hope this helps

Is gravity a variable?
Gravity is a constant not a variable. (stays constant at 9.8ms/s in earths atmosphere)
When a car rounds a corner going at constant speed is its acceleration is zero?
centripetal acceleration must be considered. dont forget gravity!
Would a rocket travel at a constant speed?
Assuming its engines are off, it would travel at a constant speed ONLY if there is no force of gravity that changes its velocity. In practice, there are always forces that will change its velocity, at least in the long term.
