The velocity of a car - or of any object for that matter - can only be changed as a result of a force applied to the car.
========================
On pressing the accelerator the pistons in the engine starts to move faster which accelerates the rotating gears attached to the wheels thus making the wheels rotate faster pushing the car's velocity up.

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 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 causes the change in velocity?
A change in velocity can be caused by forces acting on an object. These forces can be due to interactions with other objects, such as a push or a pull, or due to internal processes like propulsion systems. Changes in velocity can also occur due to changes in direction, such as when an object turns.
When cars are changing direction they are also changing what?
When cars are changing direction, they are also changing their velocity vector, which includes speed and direction. This change in velocity requires acceleration, which can be in the form of turning left or right, slowing down, or speeding up.
What control causes a change in volocity?
A resultant force causes a change in velocity.

What can forces cause a change in?
A force causes an acceleration. That implies that it will change: * The velocity, and * The momentum.

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]
What is the force that causes a change of velocity when acting on an object?
Opposing force
Why is an object traveling in a circular motion?
acceleration is change in velocity.. and velocity constantly changes in circular motion, as the direction constantly changes. This constant change in velocity causes the object to accelerate.
What causes the change in velocity?
A change in velocity can be caused by forces acting on an object. These forces can be due to interactions with other objects, such as a push or a pull, or due to internal processes like propulsion systems. Changes in velocity can also occur due to changes in direction, such as when an object turns.
How is friction a force?
Due to friction velocity of a body gets reduced, reduction in velocity causes change in velocity. This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude). And only a force can cause the acceleration hence friction is a force.
