Can the velocity of object reverse direction when its acceleration is constant?
yes, if the acceleration is in the opposite direction of the velocity.
What has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.
What has a velocity and acceleration vector in the same direction?
Any falling object has acceleration and velocity vectors in the same direction.
What is the difference between acceleration and velocity?
-- 'Velocity' is the rate at which position is changing, and the direction of the change. -- 'Acceleration' is the rate at which velocity is changing, and the direction of the change.
Is an object going in circles at a constant speed an accelerated motion?
Yes. Acceleration is the change in velocity, and velocity is a vector, which means it has direction. Because an object undergoing uniform circular motion is changing direction, it is changing velocity, and thus, accelerating.
Can the velocity of object reverse direction when its acceleration is constant?
yes, if the acceleration is in the opposite direction of the velocity.
What does acceleration have to do with velocity?
Velocity is speed in a given direction Acceleration is the rate in which you change velocity.
When angular velocity decreases the direction of angular acceleration is opposite to angular velocity .why?
Take the velocity to be in positive direction. Positive acceleration increases velocity and they are in the same direction. Negative acceleration reduce velocity and they are in opposite direction. It does not matter if the motion in linear or anfular.
What is a quantity that is specified by size and direction?
. Velocity Acceleration
What has to happen to a car's acceleration and velocity for a car's speed to increase and have a positive acceleration?
The velocity has to increase in a positive direction. The increase in velocity in a positive direction is a positive acceleration.
Velocity and acceleration related?
Acceleration is the rate at which velocity is changing, with the direction of the change.
Can a body have zero velocity and still acceleration?
No. A velocity indicates a speed and direction. An acceleration is a change in speed or direction.
What has a velocity and acceleration vector in the same direction?
Any falling object has acceleration and velocity vectors in the same direction.
What are acceleration and velocity?
'Velocity' means the rate at which position changes, and the direction in which it changes. 'Acceleration' means the rate at which velocity changes, and the direction in which it changes.

-- 'Velocity' is the rate at which position is changing, and the direction of the change. -- 'Acceleration' is the rate at which velocity is changing, and the direction of the change.

What is acceleration in science?
Acceleration is any change in velocity. Velocity is the speed and direction of motion.
