The answer depends on when "then" is.
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
Negative acceleration is the state of a body whose velocity in a specified direction is becoming smaller. If you apply the brakes while driving a car, the car (and you) will undergo negative acceleration in the direction in which the car was moving.
constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.
If a car is moving 42 meters per second after 6 sectons, the average acceletion is 7 meters per second per second. It is an average, given two points of data, and it is not the instantaneous acceleration at any point in time.
-- "Acceleration" is any change of velocity.-- "Velocity" is a speed and its direction.-- "20 meters per second" is a speed, not a velocity, because it doesn't mention a direction.-- We don't have enough information to say anything about that car's acceleration.If, for example, it happens to be moving at a constant speed of 20 meters per secondon a circular track, then it has plenty of acceleration.
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.
The acceleration of a moving car is the rate at which its velocity is changing over time. It can be positive (speeding up), negative (slowing down), or zero (constant speed). Acceleration is caused by forces such as engine power, braking, or changes in direction.
If body is moving in a circle with uniform or constant speed its acceleration will be uniform as velocity i.e. to say direction is changing at every point.
The direction of acceleration in a moving car is in the direction of the change in velocity, either speeding up or slowing down.
Stepping on the brakes of a moving car is an example of
The car's acceleration is in forward direction.
false A car can have a negative acceleration and be speeding up. A negative acceleration determines the direction of the acceleration A car with forward acceleration will speed up in the forward direction A car moving forward with a negative acceleration will slow down A car not moving with a negative acceleration will speed up in the backward direction A car moving backward with a negative acceleration will speed up in the backward direction
If the speed is constant at 50 mph, then the acceleration is 0.
The car is slowing down
If the speed of the car is decreasing while the car is still moving in a straight line, this means that the velocity and acceleration are in the same direction. This is because the car is decelerating, which results in a negative acceleration in the same direction as the velocity. This negative acceleration causes the speed of the car to decrease over time.
Well, it depends on the environment, but say we are in the most perfect environment, flat, constant friction, no air resistance, no resistance on the car's internal workings, then yes, but say it was going 30 Km/h, then it would keep accelerating until it reached 30, then it would just keep moving at 30 Km/h
No. Definitely not
