How is acceleration different from velocity?
Position is the place where an object is located. Speed is the rate at which position changes. Velocity is the speed and direction of motion. Acceleration is the rate at which velocity changes, and the direction of the change. So you could say that acceleration is the rate at which (the rate at which position changes and the direction) changes, and the direction of the change.
The rate at which an object changes position is called what?
Velocity - has 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.
What is an object's speed and direction is what?
You might be referring to velocity. It is a vector physical quantity and both speed AND direction are required to define it. One can also consider velocity as the rate at which an object changes position.
The rate at which the position of an object changes is it's?
Speed, which is distance divided by time
What are the similarities and differences between speed velocity and acceleration?
Velocity is speed with a direction. Acceleration is the rate at which velocity changes, just as velocity is the rate at which position changes (and jerk is the rate at which acceleration 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.
What is velocity in a up or down direction?
Velocity if the rate of change in an objects position. If an object moves up or down, its velocity changes. So velocity happens in both directions.
What is the physics definition of velocity?
In physics, velocity is the measurement of the rate and direction of change in the position of an object.
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.
How is motion related to acceleration?
Acceleration is one of the units with which motion is described. It's the rate at which the speed of an object changes, and the direction in which the speed changes.
What measures velocity?
In physics, velocity is the measurement of the rate and direction of change in the position of an object. Displacement of air is what it is called.
An object at rest has this velocity?
Velocity is defined as the rate of change of the position of an object in relation to the specification of its speed and direction of motion. Therefore, an object at rest will have zero velocity.
What changes occur in position direction and speed of an object when it is acted on by an unbalanced force?
the rate of change of momentum is directly proportional to the net disbalanced force and occurs in the direction in which the force acts - (newton's 2nd law) basically, it accelerates in the direction of the net force acting on the body.
How acceleration is different from velocity?
Velocity is the rate at which location changes, and the direction in which location changes. Acceleration is the rate at which the size of velocity changes, and the direction in which velocity changes.
What is the rate at which the velocity of an object changes over time?
Acceleration is the rate at which the velocity of an object changes over time.
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 is the deffinition of acceleration?
The rate at which speed changes, and the direction in which it changes.
The velocity of an object is the rate of change of its position What is it?
Velocity is the rate of change of the position of an objec
Cite an example of something that undergoes acceleration while moving at constant speed?
In physics, acceleration is defined as a change in velocity. Velocity is the measurement of the rate (or speed) and direction of an object. Therefore, an object is "accelerating" when it changes direction while maintaining the same rate (or speed).
The rate at which an object changes velocity and or directions?
Acceleration is the rate of change in velocity. (Velocity is speed+direction, it is a vector as well as acceleration). F=ma, where a is in ms^(-2).
Is the rate at which an object changes velocity?
No, velocity is the instantaneous speed of an object, the rate of change would be the acceleration of the object.
What is rate of change of position?
Rate of change of position = speedIf you also reveal the direction of the speed, then you have velocity.
Is acceleration the rate at which an object covers a given distance?
No. It's the rate at which a object changes velocity (speed).
