# Question: Under What Conditions Will The Force Exerted By The Road On The Car Be Zero Explain.?

## What is the force exerted by the road on the car?

The only two external forces acting on the car are its weight w and the normal force of the road N. (A frictionless surface can only exert a force perpendicular to the surface—that is, a normal force.)

## What happens if the resultant force is zero?

According to Newton’s First Law of motion, an object remains in the same state of motion unless a resultant force acts on it. If the resultant force on an object is zero, this means: a moving object continues to move at the same velocity (at the same speed and in the same direction)

## Under which of the following conditions is the net force on an automobile on a straight level road equal to zero?

Answer: Since the car is in uniform motion (at constant speed in a straight line), it is not accelerated, and the net force must be zero.

## What forces are acting on the car if the car is on a table and tied to a weight?

Force of gravity on car is often called its weight. Force of gravity on Earth due to car. This is the third-law partner— equal and opposite in direction— of the gravity force on the car.

## 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 Fe acts to the right and Ff acts to the left. The net force is ΣF = Fe – Ff.

## Can the resultant of two forces be zero?

All forces acting on an object add to zero: the resultant force is zero.

## Will the next force be equal to zero?

The net force is the vector sum of all the forces acting on an object. 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 force is equal to zero?

The object or system is motionless because all of the forces balance to zero. The sum of the forces is equal to the mass times the acceleration. The 2nd law tells us that if the object or system is motionless, the acceleration is equal to zero. Therefore the sum of the vector forces must be equal to zero.

## What are 4 examples of force and motion?

Climbing, jumping, running, chasing, throwing, and sliding all use force and motion.

## Does Newton’s third law apply if a system is accelerating?

According to Newton’s third law, the forces on the two objects are equal in magnitude. In a collision, there is a force on both objects that causes an acceleration of both objects. The forces are equal in magnitude and opposite in direction, yet the least massive object receives the greatest acceleration.

## What does inertia make all objects want to do?

Law of Inertia Objects want to stay in rest or motion unless an outside force causes a change. For example, if you roll a ball, it will continue rolling unless friction or something else stops it by force.

## What is Newton’s third law equation?

Newton’s third law The third law states that all forces between two objects exist in equal magnitude and opposite direction: if one object A exerts a force FA on a second object B, then B simultaneously exerts a force FB on A, and the two forces are equal in magnitude and opposite in direction: FA = −FB.

## What is the only thing inertia depends on?

Inertia is that quantity which depends solely upon mass. The more mass, the more inertia. Momentum is another quantity in Physics which depends on both mass and speed.

## Which force is responsible for holding a car in an unbanked curve?

When a car moves at a steady speed around an unbanked curve, the centripetal force keeping it on the curve comes from the static friction between its tires and the road.
