# What Is The Net Force Acting On A Car Cruising At A Constant Velocity Of 70 Km/h On An Uphill Road?

## What is the net force at constant velocity?

When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero. A vector can only have zero magnitude if all of its components are zero.

## What net force is required for a car to move at a constant speed?

(a) The car moving to the right with constant speed is moving with constant velocity. The acceleration is zero. The total force on the car is zero.

## What is the magnitude of the net force acting on a car moving with a constant velocity of 30 km/h on rough road?

Since car is moving with a constant velocity, the net force on the car is zero.

## Is constant speed a balanced force?

If the forces are unbalanced, the object will either speed up or slow down. The reverse logic is also true: if an object has a constant velocity, then the forces are balanced. And if an object is speeding up or slowing down, the forces are unbalanced.

## Can a body have acceleration with zero velocity?

Answer: Yes, an object can have zero velocity and still be accelerating simultaneously. While observing the object, you will find that the object will continue to move forward for some time and then stops instantly. Then the object will start to move in the backward direction.

## What is 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.

## Is the net force on the moon zero?

(a) the net force on it is zero. (b) it is beyond the main pull of the Earth’s gravity. Moon is orbiting the Earth with very high tangential velocity. If the Moon’s orbital speed becomes zero, it will not be able to rotate around the Earth; rather it would fall directly to the Earth.

## Can you move with constant speed and not constant velocity?

No, it doesn’t. Velocity is a vectorial quantity, it has magnitude (speed) and direction. Even though the speed is constant in this particular example, the direction changes all the time. The velocity of an object changes when the net force acting on it is not zero.

## In which direction is this force acting?

The force is acting in a sideways direction, perpendicular to both the velocity and the,agnetic field. The direction of force is given by the right hand rule.

## How do you calculate force normal?

The weight of an object equals the mass of the object multiplied by the acceleration of gravity. Multiply the two values together. In order to find the normal force, you need to multiply the weight of the object by the cosine of the angle of incline.

## How do you find the net force?

Net force is the sum of all forces acting on an object. The net force can be calculated using Newton’s second law, which states that F = ma, where: F is the net force. m is the mass of the object.
