Which most likely could cause acceleration? check all that apply. a flat road wind water movement a hill a stop light

Explanation:

Acceleration of an object is defined as the rate of change of velocity. The acceleration of an object is a vector quantity. It is caused whenever there is change in speed and the change in direction of motion of an object.

Option (1) : On a flat road, there is no chance for the change in speed or the change in direction of an object until the driver wants. As a result, on a flat road no acceleration is caused.

Option (2) and (3) : In case of Wind and water movement, it can change the speed of an object. As a result, vehicle will accelerate.

Option (4) : As the hill have curved roads, the direction of a vehicle changes. As a result, acceleration is caused.

Option (5) : A stop light, A stop light consists of three lights i.e. red light, green light and yellow light. As a light turns to red, the vehicle will decelerate and as it turns green, the driver will accelerate the vehicle.

Hence, Wind, water movement, a hill and a stop light can cause acceleration.
