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.
The direction of acceleration in a moving car is in the direction of the change in velocity, either speeding up or slowing down.
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.
The acceleration of a car moving in a circle with uniform speed is directed towards the center of the circle and is called centripetal acceleration. This acceleration is given by the formula a = v^2/r, where v is the speed of the car and r is the radius of the circle.
You have acceleration any time a velocity changes - like when an object falls down due to gravity, when a car starts or stops, when you start moving or stop moving, etc.
The answer depends on when "then" is.
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.
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
