It is directly proportional to the force applied by the engine adjusted for the frictional force, aerodynamic drag, and inversely proportional to the mass of the car.
There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.
The direction of acceleration in a moving car is in the direction of the change in velocity, either speeding up or slowing down.
The answer depends on when "then" is.
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.
The acceleration of a car moving with uniform acceleration will remain constant. This means that the rate of change of its velocity will be consistent over time, resulting in a steady increase or decrease in speed.
No. Definitely not
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.
