What else can I help you with?
The rate at which an object changes position is called what?
A change in position in a certain amount of time is called motion.
What is the decrease in speed?
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 speed changes does its velocity change?
When the object is acted upon by an outside force.
Force can cause an object to change its speed and or direction?
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.
What does a object do when it accelerates?
when the motion of an object accelerates it either increases speed, decreases speed, or it changes direction.
What is the deffinition of acceleration?
The rate at which speed changes, and the direction in which it changes.
Compare and contrast speed and acceleration?
-- "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.
What is the rate at which speed and direction 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.
What is the difference between acceleration and velocity?
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.
What is a measure of both speed and direction of an object?
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.
What changes as an object moves with a constant acceleration?
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.
Why does your car stalls while accelaration?
the rate at which velocity changes velocity=speed in a given direction
What happens to the speed of an object that is accelerating?
The speed may, or may not, change. Acceleration means that the velocity changes; this means that either the speed changes, or the direction.
What is a measurement that includes both speed and direction called?
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.
What does a measure of both the speed and direction of a moving object?
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.
Why the speed of an object is constant while the velocity is not?
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.
What is the definition of velocity?
Velocity is a measure of the speed of an object that is moving in a specific direction.Imagine walking across the room. If you walk in the same direction and do not change speed, your velocity remains constant until you stop moving. If you keep a constant speed, but change direction while walking, your velocity changes. If you walk in the same direction but slow down and speed up while walking, your velocity changes. Velocity is a vector quantity that describes the speed and direction that an object is moving. It is the same as "speed" except that it includes the direction of the object as well. Speed is the rate of change of distance.In common language, velocity is often used imprecisely to mean "speed".
