A train approaching a crossing changes speed from 25 meters per second to 10 meters per second in 240 seconds how can the train's acceleration be described?

Acceleration = (change in speed) / (time for the change)
= (10 - 25) / 240 = -15/240 = -0.0625 meter/sec2
The acceleration is negative, which is a description of slowing down.

Can be defined as the rate at which velocity changes?
accelerationThe rate at which velocity changes is called "acceleration".
Is acceleration the same as speed?
Acceleration is the rate that speed changes.
What is defined as the rate at which velocity changes?
acceleration
What describes a trains acceleration if it changes speed from 25 m s to 10 m s in 240 s?
negative Acceleration
What is the acceleration of a car that travels in a straight line at a constant speed of 80 km per hour?
if the velocity is constant, the acceleration is zero. The acceleration is the rate at which the velocity changes, so if it stays the same, the car isn't accelerating.
What can acceleration be described as?
Acceleration can be described as the rate at which an object's velocity changes over time. It measures how quickly the object's speed or direction is changing. Therefore, it quantifies how much an object's motion is increasing or decreasing.
Why at a constant speed if an object changes its direction it is considered to be acceleration?
Acceleration is a direction plus a speed. If either changes then the acceleration changes.
What is the rate at which an object velocity changes?
Acceleration
What makes a change in velocity?
A force on a material object.The change in velocity per second is (the force) divided by (the object's mass).
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 the rate at which speed or direction changes?
Acceleration
Can be defined as the rate at which velocity changes?
accelerationThe rate at which velocity changes is called "acceleration".
Is acceleration how quickly an object's velocity changes?
Yes, acceleration is the how the velocity changes. This also includes when an object turns
Is acceleration the same as speed?
Acceleration is the rate that speed changes.
Whats acceleration what is acceleration?
Acceleration is the rate of change of velocityaka how fast the velocity changes
What is the acceleration of?
There is no force of acceleration. Acceleration is the rate at which velocity changes over time. A net force causes acceleration.
Is it possible for a body to have an acceleration when moving with constant velocity?
No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.No; acceleration means the velocity changes.
