The forces that act on a vehicle are
- Drag (Mechanical friction)
- Gravity
- Thrust
- Lift
Static and dynamic frictions
Static friction
The force that prevents an object from starting to move. Example, a block sliding down a slope. In the initial force required to overcome this is dependent on Mass and the frictioncoefficient.
Dynamic friction
The forces that occur when two objects move in relation to each other. The car and the road or the car and the air are examples of this.
Such as:
Lift
Lift is thevehicle'stendencyto want to become airborne. This is dependent on it's aerodynamic shape, speed and mass. Downforce created by increasing air resistance at the expense of acceleration fuel consumption and top speed is crucial in the design of cars.
Inertial friction
resistance to motion (Newtons first law) The friction needed to be overcome tostartthe vehicle rolling. Torque from the engine is needed to start the car moving. You might want to check out Newtons first law of motion.
Mechanical friction
The internal workings of the car such as bearings, gearing, tyres on the road air friction (see drag) etc. This reduces engine efficiency, increases fuel consumption.
Mass & Gravity
The mass of the object defines the effect of gravity. Gravity acts on the car at 9.81metersper second. This force affects both acceleration (F=M*a) anddeceleration andinfluencesspeed when on an incline or decline.
Thrust
This is the amount of force generated by the engine whichpropelsthe vehicle forward. This conforms to Newtons second law.
The acceleration a of a body is parallel and directly proportional to the net force F acting on the body, is in the direction of the net force, and is inversely proportional to the mass m of the body, i.e., F = ma.
In plain English this means that to accelerate you have to add force.

Are there forces acting on a car that is at rest xy?
There are forces acting on the car. They are just equal to the force of the car acting on the force. In example, gravity is acting on the car, but the car is pushing back equally. Therefore, the car doesn't move.
What forces are acting on a moving car?
Friction
You are sitting in a car driving at a constant speed on a flat road What are all of the forces acting on you not the forces acting on the car?
Moving at a constant speed if your in the car then there are no forces acting on you from the car. If the car accelerates then the car will push you forward and you will feel the Force of the seat pushing you. The only other force on you in a car is gravity witch always pulls straight down. Gravity is always there whether the car is accelerating or not.
If a car is not moving what forces are acting on it?

Are there forces acting on a car that is at rest?
Yes, gravity is constantly acting on all objects even when they are at rest.

what about it?lolololololol

What effect does streamlining have on the friction forces acting on a car?
safyans mum ;)
If the sum of all the forces acting on a car is zero then the speed of the car always?
The speed of the car is constant. For more information try searching "Newton's laws of motion".
When a car travel around a curve in the road what helps to keep the car traveling in a curved path?
the force that the car has acting on it counteract in a perfect balance with the forces acting against it.
What do you say if you're in the mood to correct the mistaken statement of a friend xy?
There are forces acting on the car. They are just equal to the force of the car acting on the force. In example, gravity is acting on the car, but the car is pushing back equally. Therefore, the car doesn't move.
Is it possible for a car moving with a consonant velocity to have forces acting on it?
Yes...gravity
If a car is moving at a steady speed of 50 mph what forces will be acting on it?
65
