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 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.
Is stepping on the brakes of a car acceleration. That would be deceleration.
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.
You need the initial and final velocities, and time interval to answer this question.
a car become positively active when we can notice that there is an acceleration.
"Constant rate" implies there is no acceleration - acceleration is zero.
