## What is the network done by the external force on the car moving with a constant speed on a straight line?

No, when a car is moving with constant speed on a straight road net-work done by external forces will be zero. Q. Solve the following problems.

## When your car moves along the highway at constant velocity the net force on it is zero WHy then do you continue running your engine?

When your car moves along the highway at constant velocity, the net force on it is zero. WHy do you have to keep running your engine? You have to have on the engine to remain at constant velocity because if it’s shut off there is going to be friction causing the car to slow down.

## What is the answer to a car moving with a constant speed?

A car moves with constant speed on a straight path. So it is said to be in rotatory motion.

## Is a car moving at a constant speed in a straight road acceleration or not?

Acceleration is defined as rate of change of speed So, if car is moving with constant speed that means rate of change of speed is zero. Hence, acceleration is zero.

## What is the force of a car at a constant speed?

To maintain constant velocity of car,the net force acting on car should be zero. for this The force applied by the engine to maintain its velocity should be equal to total frictional force of is acting on the car. i.e;5000 N.

## When a car is Travelling at a constant speed the forces on it are?

A car traveling at constant velocity is said to be in mechanical equilibrium. In that state, the car has no net torque no net force, i.e. the net force on the car is c) zero. This is because a constant velocity means that the net acceleration of the car is zero. A zero net acceleration implies zero net force.

## What is the net force of a car moving at constant velocity uphill?

Regardless of the direction, if an object has uniform velocity (moving with the same speed in one direction) the net force on the object will be zero.

## What is the net force on an object moving at constant speed in a circular path?

For objects moving in circles at constant speed, the net force is directed towards the center of the circle about which the object moves. Such a direction is described as being centripetal.

## What will happen to a car moving at constant speed if all forces acting on it are balanced?

A force, in very simple terms, is something that changes the motion of an object. If there is no net force acting on an object its motion won’t change. So if it is moving with a constant speed and no net force acts on it the object will continue with it’s motion.

## What is an example of moving at a constant speed?

Constant motion is a type of motion that occurs when either the distance traveled by the object is the same for each second or the speed of the object changes by the same amount each second. A car maintaining a speed of 20 meters per second as it moves in a straight line for 5 seconds is in constant motion.

## What is the meaning of moving at a constant speed?

Definition: When the speed of an object remains the same – it does not increase or decrease – we say it is moving at a constant speed.

## When an object travels along a path at a constant speed?

An object travels along a path at constant speed. There is a constant net force acting on the object that remains perpendicular to the direction of the motion.

## What is the net work done to the car if it moves at a constant speed Why?

Per the work energy theorem the net work done on an object equals its change in kinetic energy. Therefore the net work on an object moving at constant velocity is zero.

## What is the net external force acting on a car traveling westward with a constant velocity of 20m s?

The resultant force is zero, as the acceleration is zero.

## What are the external forces acting on a car?

In short, the external force responsible for a car moving forward or backward is the static friction force, and is always in the same direction as the car’s movement.

## What is the net work done on a car Travelling horizontally at a constant speed?

At constant velocity, there is no change in kinetic energy, so the net work done to move the car is zero. Therefore the power supplied by the engine to move the car equals the power expended against gravity and air resistance.
