What are the Forces on a Moving Car? The forces acting on a moving car are thrust and drag as well as the same forces that act on a stationary car. Drag is the force of air resistance (a form of friction) pushing against the front of the car while it is moving. Thrust is the force pushing the car forwards. Thrust comes from the engine turning ...
List the various types of friction. Calculate the magnitude of static and kinetic friction, and use these in problems involving Newton’s laws of motion. When a body is in motion, it has resistance because the body interacts with its surroundings. This resistance is a force of friction.
Friction is a force that opposes relative motion between systems in contact. One of the simpler characteristics of friction is that it is parallel to the contact surface between systems and always in a direction that opposes motion or attempted motion of the systems relative to each other.
For example, when a car travels at a constant speed, the driving force from the engine is balanced by resistive forces such as air resistance and friction in the car's moving parts.
If two systems are in contact and moving relative to one another, then the friction between them is called kinetic friction. For example, friction slows a hockey puck sliding on ice. When objects are stationary, static friction can act between them; the static friction is usually greater than the kinetic friction between two objects.
