1. Accelerating objects are objects that are changing their velocity. Name the three controls on an automobile that cause it to accelerate.

Velocity is speed and its direction. Acceleration is any change of speed or direction. The gas pedal, the brake pedal, and the steering wheel can all cause that change.

In an automobile, acceleration can be achieved through three main controls: the gas pedal for increasing speed, the brake pedal for decreasing speed, and the steering wheel for altering direction, all of which change the car's velocity.
Acceleration in a vehicle occurs when there is a change in velocity, which can be in the form of an increase or decrease in speed, or a change in direction. Three controls on an automobile that cause it to accelerate are the gas pedal, the brake pedal, and the steering wheel. Pushing down on the gas pedal increases the flow of gasoline to the engine and results in the car speeding up. Conversely, pressing on the brake pedal reduces speed, thereby changing the velocity. The steering wheel, when turned, changes the direction of the car, which also constitutes acceleration even if the speed remains constant.
Summary of Acceleration Controls:

The Gas Pedal: Pressing it down increases the car's speed, causing acceleration.
The Brake Pedal: Applying the brakes decreases the car's speed, also resulting in acceleration due to the change in velocity.
The Steering Wheel: Turning it changes the car's direction of travel, leading to acceleration as the direction component of velocity changes.

In an automobile, the gas pedal, brake pedal, and steering wheel are three controls that cause acceleration. The gas pedal increases speed, the brake pedal slows down the car, and the steering wheel changes direction. All three result in a change in velocity, defining acceleration.
