Speed and acceleration are covered thoroughly in the first semester of
Freshman Physics, and rather early in the semester at that. These are
no longer topics in which there's a lot to be gained by a PhD specializing
in them.
Acceleration is the time rate of change of speed. Acceleration = speed/time.
Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.
Acceleration is the rate that speed changes.
You can calculate speed by dividing the force by the mass to get acceleration, and then multiplying the acceleration by time. Speed = acceleration x time.
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
If you have a negative acceleration, you are slowing down. Acceleration is the rate of change of speed, so a negative acceleration means a decrease in speed.
To find speed using acceleration and time, you can use the formula: speed acceleration x time. Simply multiply the acceleration by the time to calculate the speed.
Average acceleration = Change in speed/time so Time = Change in speed/Average acceleration
Speed = Time x acceleration
A change in speed (and/or direction) is acceleration.
speed equals to acceleration into time
acceleration times speed
