Acceleration
A change in position in a certain amount of time is called motion.
When speed changes, the rate a which you are going (ex: 22 miles per hour) changes. Direction changes when the direction(ex: north, south, east, west) changes. Any change in speed or direction of motion is known as 'acceleration'.
When the object is acted upon by an outside force.
yes, because force is a push or pull, so an example would be that wind (the force) pushed the bike faster toward a building and steered the bike around the building, which causes the bike to change direction. This is an example of velocity too. Velocity is speed in a specific direction.
when the motion of an object accelerates it either increases speed, decreases speed, or it changes direction.
The rate at which speed changes, and the direction in which it changes.
-- "Speed" is the rate at which distance changes. -- "Velocity" is speed along with the direction of motion. -- "Acceleration" is the rate at which velocity changes, including the direction of the change.
The rate at which speed changes is acceleration, which is the change in velocity over time. The rate at which direction changes is angular acceleration, which is the change in angular velocity over time.
Velocity is the rate at which an object changes its position, while acceleration is the rate at which the velocity of an object changes. In other words, velocity is the speed and direction of motion, whereas acceleration is the change in speed or direction of motion.
Velocity is a measure of both speed and direction of an object. It indicates the rate at which an object changes its position in a particular direction over time.
During constant acceleration, either the object's speed changes at a constant rate, or the direction of its motion changes at a constant rate, or both.
the rate at which velocity changes velocity=speed in a given direction
The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
A measurement that includes both speed and direction is called velocity. Velocity is a vector quantity that describes the rate at which an object changes its position, including the speed at which it moves and the direction in which it moves.
A measure of both the speed and direction of a moving object is known as velocity. Velocity is a vector quantity that defines both the rate at which an object changes its position (speed) and the direction in which it is moving.
'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.
This is not always the case. But if an object moves in a circle, at constant speed, its velocity will change. Velocity is a vector - consisting of the magnitude (the speed), and a direction. So by definition, if the direction changes, the velocity changes - you have a different vector.
