Acceleration is the change in velocity. Velocity is the change in speed or direction. Therefore, acceleration is changing the change in speed or direction. So if you are going at 50mph and then you are going at 55mph and then at 60mph, your acceleration is constant at 5 mph. if the change in accleartion is changing, then it is not constant. If you turn dirctions even while you move at a constant velocity, you are accelerating.

What force decreases the acceleration of two objects moving against each other?
The force that decreases the acceleration of two objects moving against each other is the gravitational force.
What is the direction of average acceleration?
The direction of average acceleration is downwards, in the direction of gravity. This is because gravity affects all objects, even objects that are moving in other directions.
What force decresses acceleration of two objects moving against each other?
friction
What must you know about an object that is moving in a straight line to calculate its acceleration?
You must know its mass and the net force. If it is moving at constant velocity, the net force is zero and the acceleration is zero.
What depends on an objects mass and velocity?
An objects acceleration depends on its mass and the force acting on it. Newton's second law, F = ma.
What force decreases the acceleration of two objects moving against each other?
The force that decreases the acceleration of two objects moving against each other is the gravitational force.
What causes the acceleration of moving objects?
Force is the only thing that causes the accelerationof material objects, whether they're moving or not.
Why do moving objects always undergo acceleration?

What force decresses acceleration of two objects moving against each other?
friction
When velocity is negative and acceleration is positive what happens to an objects motion?
Its slowing down (but still moving).
When you know both the speed and direction of an objects of an objects motion you know the?
I'm pretty sure its the acceleration. If its not that, its the Velocity.
What must you know about an object Moving in a straight line to calculate its acceleration?
You must know its mass and the net force. If it is moving at constant velocity, the net force is zero and the acceleration is zero.
What must you know about an object that is moving in a straight line to calculate its acceleration?
You must know its mass and the net force. If it is moving at constant velocity, the net force is zero and the acceleration is zero.
Why do things quickly?
Acceleration due to gravity, -9.81 m/s^2, is just like any acceleration. As time continues, a moving objects speed increases.
When velocity is positive and acceleration is zero what happens to an objects motion?
When acceleration is zero, then the object is moving in a straight line with constant speed. (That's the effective meaning of constant velocity.)
Why do things fall quickly?
Acceleration due to gravity, -9.81 m/s^2, is just like any acceleration. As time continues, a moving objects speed increases.
