Gravity: Gravity is a force that acts on all objects with mass, including vehicles. Gravity is what keeps a vehicle's wheels on the road and helps to stabilize it while in motion.
Friction: Friction is the force that opposes motion between two surfaces in contact. Friction between the tires and the road is what allows a vehicle to accelerate, brake, and turn.
Air resistance: Air resistance, also known as drag, is the force that opposes the motion of an object through the air. The shape and size of a vehicle can greatly affect the amount of air resistance it experiences.
Centrifugal force: Centrifugal force is the force that acts on an object moving in a circular path. In a vehicle, centrifugal force can cause it to lean to the outside of a turn, making it feel like the vehicle is being pulled to the side.
Inertia: Inertia is the tendency of an object to resist a change in its state of motion. A vehicle's inertia can make it more difficult to start or stop, especially if it is moving at a high speed.
Wind: Wind is the movement of air and can affect the handling of a vehicle, especially if it is strong or gusty. Strong winds can push a vehicle off course or make it difficult to control.
Road conditions: The condition of the road, such as the presence of ice, water, or loose gravel, can greatly affect the handling of a vehicle. Different road surfaces can also affect the amount of friction between the tires and the road, which can impact the vehicle's ability to accelerate, brake, and turn.
