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'.
The rate at which an object changes position is called what?
A change in position in a certain amount of time is called motion.
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 changes speed and direction?
Velocity is defined as a vector quantity representing both speed and direction. Acceleration is defined as the rate at which velocity changes. The acceleration of an object changes when it is acted upon by an unbalanced force.
What changes if someones speed or direction changes?
The acceleration changes if speed or direction changes
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 kind of motion occurs when velocity and acceleration are not in the same direction?
You are confusing terms.Acceleration is the rate at which an object changes speed.Velocity is a combination of speed and 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.
Compare and contrast acceleration and velocity?
-- "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.
Why at a constant speed if an object changes its direction it is considered to be acceleration?
Acceleration is a direction plus a speed. If either changes then the acceleration changes.
How is it possible for a moving car velocity to change but the speed to stay constant?
Velocity is a vector (has a size and a direction) but speed is a scalar (just a number). The velocity is therefore given by the speed and the direction the speed is going. If you change the direction but continue at the same rate the velocity changes but the speed doesn't
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'.
