There is only acceleration if the car's velocity changes. If it moves at a constant velocity, then there is no acceleration.

Q: Why is it that their is an acceleration when a car is moving?

If the speed is constant at 50 mph, then the acceleration is 0.

My interpretation is that the car and any motion, like the graph, do not exist.

The van that is moving from 20 mph to 35 mph

Acceleration is zero since 55 mph is velocity and it is constant. Acceleration is defined as the rate of change in velocity. The speed is the absolute value of velocity so it is also 55.

As long as the 30 minute are spent driving in a straight line, the acceleration is zero.

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.

No, stepping on the brakes of a moving train is an example of deceleration, as it is the action of slowing down or reducing the speed of the train. Acceleration refers to an increase in speed or velocity.

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.

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 moving car can become positively charged through processes like friction, which can cause the transfer of electrons between the car and another object. For example, when the car drives on the road, friction between the tires and the ground can result in the car gaining a positive charge if electrons are transferred from the road to the car.

"Constant rate" implies there is no acceleration - acceleration is zero.
