## 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.

## How do you calculate the net force of a moving car?

If the car is moving to the right and to the right is taken to be the positive direction, then F_{e} acts to the right and F_{f} acts to the left. The net force is ΣF = F_{e} – F_{f}.

## 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.

## 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.

## What are the forces that act on the ball?

Answer: The forces are the weight, drag, and lift. Lift and drag are actually two components of a single aerodynamic force acting on the ball. Drag acts in a direction opposite to the motion, and lift acts perpendicular to the motion.
