Question

is depressing (or compressing) the gas pedal of a car the only way that a driver can make a car accelerate? ignore external forces such as friction, wind force, gears shifting, or potential collision forces.

multiple choice

no. the driver can also cause the car to accelerate by changing its direction of motion.

yes. by only depressing (or compressing) the gas pedal, the car will slow down (or speed up), which generates an acceleration.

no. as long as the car is not stationary, it is always accelerating.

yes, but one needs to apply the brakes firmly and release them quickly.

Explanation:

Acceleration is a change in velocity (speed or direction). Turning (changing direction) also accelerates the car, so the gas pedal isn't the only way. Other options are incorrect: B misdefines acceleration; C confuses motion with acceleration; D is about braking, not acceleration.

Answer:

A. No. The driver can also cause the car to accelerate by changing its direction of motion.
