Which force is responsible for holding a car in a frictionless banked curve and in an unbanked curve respectively?

This force must be the centripetal force! This friction force points toward the center of the turn, and is responsible for turning the car. So, in an unbanked turn, the force responsible for turning the car is the friction force between the tires and the road.

Which claim about the forces acting on the ball must be true?

A net force greater than zero acts on an object. Which claim about the forces acting on the ball must be true? There is a net force on the ball.

When a force is exerted on an object no work done if the object?

A force acts upon an object at a 90-degree angle to the direction that it is moving. This force is doing negative work upon the object. An individual force does NOT do positive work upon an object if the object is moving at constant speed.

What are the forces acting on a car accelerating?

When the car accelerates , there is a horizontal forward force on the car, and a corresponding backwards horizontal force on the ground. As the car picks up speed, air resistance produces a backwards force. On the diagram we have drawn some forces offset from the center of mass, so that the vectors don’t overlap.

What force holds a car on a frictionless banked curve?

Which force is responsible for holding a car in a frictionless banked curve? The answer is the horizontal component of the normal force.

Which force is responsible for holding a car in a curve?

Centripetal Force
Centripetal Force and Curved Paths: The centripetal force is responsible for this change.

What can you conclude about the forces acting on an airplane if it is maintaining constant altitude constant speed and constant direction?

In terms of airplane flight, the two main forces influencing its velocity forward are drag and thrust. At a constant altitude, when the force of thrust equals the opposing force of drag, then the airplane will experience uniform motion in one direction. This can be further explained by Newton’s First Law.

When a force is exerted on an object What happens to the object?

A force exerted on an object can change the object’s velocity. Force also causes moving objects to stop or change its direction. All of these changes involves a change in velocity – acceleration. The SI unit for force is the newton.

Is work done whenever a force is exerted?

Whenever a force is applied to an object, causing the object to move, work is done by the force. If you move the book at constant speed horizontally, you don’t do any work on it, despite the fact that you have to exert an upward force to counter-act gravity.

What force is used on a car?

Many Forces When the car is sitting still, gravity exerts a downward force on the car (this force acts everywhere on the car, but for simplicity, we can draw the force at the car’s center of mass). But the ground exerts an equal and opposite upward force on the tires, so the car does not move.
