What best describes the difference between speed and acceleration?

∙ 10y ago
Speed is the measure of distance covered in specific time - 7 metres in 2 seconds or 45 kilometres in 1 hour
Acceleration is the change in velocity
Acceleration is measured in metres per second per second (m/s/s)
Velocity is speed with direction (5 m/s [North]) or 12 m/s [South 32° West]
Not speed itself
If a Formula 1 cars starting velocity is 0m/s (metres per second)
And its final velocity is 27m/s
The difference is 27m/s
If this change happened in 3seconds
Acceleration = 27 / 3
Acceleration = 9m/s/s

∙ 11y agoVelocity is the speed that an object travels at, e.g. metres per second
Acceleration is the change in speed over time ('speeding up' or 'slowing down'), eg. metres per second per second

∙ 12y agoSpeed is the rate of change in distance, whereas velocity is speed and direction of travel. Acceleration is the change in velocity (including direction).

∙ 15y agoMotion describes that something is moving. Speed describes how fast something is moving. Velocity describes how fast something is moving and in what direction its moving.

∙ 7y agoThis can better be stated in terms of VELOCITY and acceleration. Acceleration is the rate of change of velocity, i.e., how quickly it changes - in symbols: a = dv/dt.

What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
What is the Difference between Uniform motion and uniform acceleration?
"Uniform motion" means constant velocity ... constant speed in a straight line. "Acceleration" means any change in velocity ... speed or direction. So 'uniform motion' means zero acceleration.
How is increasing speed acceleration?
By definition acceleration is the change in velocity (speed).
What happens to acceleration when speed decreases on a speed time graph?
Acceleration is negative.
The slope of a speed vs time graph is equal to what?
Acceleration.
What is the difference between constant speed and constant acceleration?
Constant speed means that speed doesn't change. Constant acceleration means that acceleration doesn't change. (If the acceleration is anything but zero, speed WILL change.)
What is the difference between speed and acceleration in phisycs?
Speed - is something moving at a constant rate. Acceleration is an increase of the rate an object is moving.
What is the difference between speed velocity acceleration?
Speed is the rate of change in distance, whereas velocity is speed and direction of travel. Acceleration is the change in velocity (including direction).
What is the acceleration of a car that is going at a steady speed of 60 mph?
At a constant speed there is no acceleration. Acceleration describes a positive change in speed meaning to go faster. Deacceleration describes how fast something is slowing down. But at a constant speed of 60mph there is acceleration or deacceleration.
What describes motion of a car?
Acceleration describes the motion of a car. Acceleration is defined as an increase in the rate or speed of something.
What is the difference between acceleration and deceleration?
Acceleration means speeding up or getting faster. Deceleration means losing speed or speed rate decreasing. 'Celer' is the Latin word for fast or speedy. - Answer Deceleration is the loss in speed or slowing down. Acceleration is the increase in speed.
What is the difference between an object with constant acceleration and an object with constant speed?
Constant speed means that the speed doesn't change.Constant acceleration means that the acceleration doesn't change. The velocity WILL change in this case - unless the acceleration happens to be zero. So will the speed - note that in circular motion, both the acceleration and the velocity change all the time, even if the speed doesn't change.
What describes acceleration?
Any change of speed or direction of motion.
What is the different between motion and acceleration?
Motion is about speed of location change, acceleration is about speed change.
What is difference between an object moving with uniform acceleration and an object moving with a constant velocity?
A motion with a constant speed will always be moving the same speed A motion with a constant acceleration will constantly be gaining speed, and does not remain moving at the same speed.
When you press your bicycle's brakeswhat happens to your speedvelocityand acceleration?
your seed,velocity,and acceleration will be slow When you brake, your acceleration increases (!), your velocity decreases (and in this case, there is no difference between velocity and speed). Negative acceleration increases when braking a moving bike.
What describes a train's acceleration if it changes speed from 25 ms to 10 ms in 240 s?
Since the direction of motion is not given, nor implied by speed, the acceleration can have any value between 0.146 ms-2 and 0.0625 ms-2.
