An accelerator increases the amount of fuel going to the engine, which in turn increases the engine's power output. This increased power allows the car to overcome resistance forces like friction and aerodynamic drag, resulting in an increase in velocity.

What car control causes a change in velocity?
Applying the accelerator pedal or brake pedal can cause a change in velocity of a car. Accelerating will increase velocity, while braking will decrease velocity.
Describe a situation in which gravity causes a change in velocity why does a change in velocity happen?
When an object is dropped from a height, gravity causes it to accelerate towards the ground. This acceleration leads to a change in velocity as the object's speed increases. The change in velocity occurs because gravity exerts a force on the object, pulling it towards the Earth.
What control on a car can cause a change in velocity at constant speed?
Pressing the accelerator pedal can cause a change in velocity by increasing the speed of the vehicle even when maintaining a constant speed.
What is a situation gravity causes a change in velocity and why does the change of velocity happen?
A situation where gravity causes a change in velocity is when an object is dropped from a height. As the object falls, gravity acts on it, causing it to accelerate towards the ground. The change in velocity happens because gravity exerts a constant force on the object, causing it to increase its speed over time.
What is the force that causes the velocity of an object to change?
The force that causes the velocity of an object to change is called acceleration. Acceleration is defined as the rate at which an object's velocity changes over time, and it can be caused by various factors such as gravity, friction, or applied forces.
What car control causes a change in velocity?
Applying the accelerator pedal or brake pedal can cause a change in velocity of a car. Accelerating will increase velocity, while braking will decrease velocity.
What two controls on a car cause a change in velocity?
The cruise control, since it affects the accelerator, can also cause a change in velocity.
What control causes a change in volocity?
A resultant force causes a change in velocity.
How do you safely change a car's velocity?
Slowly press on the accelerator to go more quickly. Slowly press down on the brake pedal to go more slowly. These two operations can safely change a car's velocity.

What can forces cause a change in?
A force causes an acceleration. That implies that it will change: * The velocity, and * The momentum.
Why is the accelerator pedal in a car called by this name?
An accelerator pedal is named as such because it acts to accelerate or change the velocity of the vehicle. In most cases it causes the engine to use more fuel to act to cause a force (or something that accelerates an object) on the vehicles tires. This cause the vehicle to either speed up, or maintain a speed, or fight a deceleration.
What is the force that causes the velocity of an object to change?
The force that causes the velocity of an object to change is called acceleration. Acceleration is defined as the rate at which an object's velocity changes over time, and it can be caused by various factors such as gravity, friction, or applied forces.
How is the initial velocity zero but the acceleration is not?
Going back to definitions, Velocity is change of distance with time; and acceleration is change in velocity with time. Initially, the velocity is zero, as is the acceleration, BUT the Force of Gravity attracts the falling mass, and causes velocity to appear. But the continued application of the Force of Gravity causes the velocity to increase. And as we know, increase in velocity is acceleration. [space for QED]
How do you change velocity in a car?
To increase velocity in a car, you can press the accelerator pedal to increase the speed. Conversely, to decrease velocity, you can either release the accelerator pedal to slow down gradually or apply the brakes to rapidly reduce speed. Maintaining a safe and controlled speed is essential for safe driving.
