A car travels at 30m/s and the driver sees a stoplight turn green 35ms ahead. If the driver immeditly steps on the break, what is the minimum acceleration needed from the brakes to stop in time.
All information needed is given except final velocity which can be assumed to be zero. This is a problem I made up, if one is needed out of a textbook, look for any problem where an object is either slowing down, or moving towards the point of reference.
That would be "Deceleration" or negative acceleration.
'Acceleration' is defined as the rate of change in velocity and the direction of the change. 'Deceleration' is a popular but unscientific word used to describe acceleration with a negative magnitude, i.e. 'slowing down' without regard for its direction.
write a sentence with the word acceleration
Acceleration due to gravity is negative when an object is moving up. Accl'n due to gravity is positive when an object is moving down (since gravity acts downwards on an object). ^Acceleration due to gravity is always negative, while the acceleration of the ball upward was positive due to what threw it, not gravity.
to accel
give sample of word problem of acceleration
That would be "Deceleration" or negative acceleration.
Technically, it is acceleration either way. If something is slowing down, the acceleration is negative. Slow down or Decrease velocity
Deceleration is often referred to negative acceleration because deceleration is not AA commonly used word.

The word 'demonstrates' is a verb; the third person, singular, present of the verb to 'demonstrate'.Example: When he demonstrates the equipment, he must shout over the noise.
problem
The velocity of the car on the highway is going extremely slow.Velocity is a speed with a direction."As shown by his ability to hit 100 mph on a radar gun, the pitching prospect had a great arm, but his lack of control illustrated his need to work on his velocity."
Deceleration is not a good description except when describing linear motion in a single (forward) direction.It actually represents an acceleration of an object, but in the opposite direction of its current motion. The term negative acceleration is also imprecise.
example
The automobile has good acceleration
