Is acceleration the same as speed?
Acceleration is the rate that speed changes.
What describes a trains acceleration if you changes speed from 25 miles per second to 10 miles per second in 240 seconds?
acceleration = change in speed /time = (10-25)/240=15/240 = -1/16 The train is slowing down (decelerating) at a rate of 1/16 mile per second per second Added: Hate wasting work! Same answer in decimal. Acceleration ( looks like slow down here ) = change in velocity/change in time 10 mi/s = 25 mi/s/240 s - 0 = - 0. 0625 mi/s2 ======================long time braking
The relationship of speed and acceleration?
Acceleration is the time rate of change of speed. Acceleration = speed/time.
What is the average acceleration of a car that changes speed from 0 meters per second to 15 meters per second in 5seconds?
Average acceleration = change in speed/time for the change = 15/5 = 3 meters per second2 .
For a car moving around a circular track at a constant speed the acceleration is?
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
Is acceleration the same as speed?
Acceleration is the rate that speed changes.
Why acceleration is tangent to the path?
Acceleration is tangent to the path because it is a measure of the rate of change of velocity. By being tangent to the path, acceleration describes how the direction or speed of an object is changing as it moves along a curved path. The tangential component of acceleration is responsible for changes in speed, while the normal component of acceleration is responsible for changes in direction.
Which describes a trains acceleration if it changes speed from 25ms to 10ms in 240s?
The acceleration of the train can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Plugging in the values: (10 m/s - 25 m/s) / 240 s = -0.0625 m/s^2. The negative sign indicates that the train is decelerating.
What is the rate at which speed or direction changes?
Acceleration
How does speed interact with acceleration?
Acceleration is the rate at which speed changes, at least scalarly.
Is acceleration the fastest kind of speed?
Acceleration is a measure of how quickly the speed of an object changes over time, not the speed itself. Speed refers to the rate at which an object covers distance, while acceleration refers to how the speed of the object changes. So, acceleration is not a kind of speed, but rather a measure of how speed changes.
How does a change in speed affect acceleration?
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.
When an object changes speed does its acceleration change?
Yes, when an object changes speed, its acceleration changes. Acceleration is a measure of how quickly the speed of an object changes over time. So, if the speed changes, the acceleration of the object will also change.
What is it calledwhen an object's speed changes?
acceleration or deceleration.
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 rate at which speed changes?
Acceleration?
How does law of acceleration changes speed?
The law of acceleration states that the acceleration of an object is directly proportional to the force acting on it and inversely proportional to its mass. So, an increase in the force applied to an object can result in a greater acceleration, causing the object to change speed more quickly.
