You don't say which speed, but all change over time.
Speed is the rate of change in what?
no its speed that definds the rate change of position
No. An acceleration is not a speed. It is a rate of change of speed - that is, a change of speed, divided by the time it takes to change the speed.
Velocity is the rate of change in an object's location over time, also known as speed.
Speed is the rate of movement in any direction based on change in position for a change in time. Velocity is a change in speed. It is also a change in direction while the speed does not have to change.
speed.
Speed is the rate of change in what?
The rate of change of velocity over time is called acceleration. It can be as a result of increase or decreased speed, or change of vector.
Speed
Changes in position over time is motion, and the rate of change may be velocity or speed.
Changes in position over time is motion, and the rate of change may be velocity or speed.
no its speed that definds the rate change of position
NO! It is the rate of reactions!
The rate of change of an object's position over time is the object's speed.
No. An acceleration is not a speed. It is a rate of change of speed - that is, a change of speed, divided by the time it takes to change the speed.
Velocity is the rate of change in an object's location over time, also known as speed.
Speed is the rate of change of distance with time. Velocity is the rate of change of displacement with time.
