# Is the force that opposes the sliding motion of two surfaces that are touching each other?

## Is the force that opposes the sliding motion of two surfaces that are touching each other?

Friction – a force that opposes motion between two surfaces that are touching.

## Is the following statement true or false an object that is not accelerating or decelerating has zero net force acting on it?

An object that is not accelerating or decelerating has no net forces acting on it. True; If all the forces net out, then the object’s velocity will not change. This is just a restatement of Newton’s First Law of Motion.

## Why your velocity changes when you ride a Ferris wheel even if the wheel turns at a constant speed?

Describe why your velocity changes when you ride a Ferris wheel even if the wheel turns at a constant speed. As the Ferris wheel turns, you are moving in a different direction at each instant of time. Since the direction changes, the velocity changes.

## What depends on an object’s mass and the net force acting on the object?

The acceleration of any object depends on two things: the net force acting on it and its mass. According to Newton’s Second Law, acceleration is directly proportional to the net force and inversely proportional to the object’s mass.

## Which force opposes motion?

FRICTION: Friction is a force that opposes motion. When two objects are in contact, friction is acts in a direction opposite to the motion of the object.

## What are the two types of force that opposes motion?

There are two types of friction force: static friction and kinetic friction.

## When there is a net non zero force on a moving object?

If the net force acting on an object is non zero, then there is an acceleration or deceleration. Either the object is increasing or decreasing its speed.

## What is the formula for net force?

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. a is acceleration.

## Is net force 0 when velocity is constant?

According to Newton’s first law of motion, any object moving at constant velocity has no net external force acting upon it, which means that the sum of the forces acting on the object must be zero.

## What Newton’s law is a Ferris wheel?

You may have heard of Sir Isaac Newton and his Laws of Motion. The second Law of Motion has to do with the behaviour of objects when existing forces are not balanced. In a Ferris wheel, forces are not balanced. Objects that have circular motion have something called “centripetal force”.

## Is it true that any change in velocity for any reason is called acceleration?

A change in motion is simply a change in velocity: the speed of an object can become slower or faster, the direction in which the object is moving can change, or both of these variables may change. A change in velocity means, by definition, that an acceleration has occurred.

## Does rotation affect velocity?

The faster the tire spins, the faster the car moves—large ω ω means large v because v = r ω v = r ω . Similarly, a larger-radius tire rotating at the same angular velocity, ω ω , will produce a greater linear (tangential) velocity, v, for the car.

## What is a force between two surfaces that are sliding across each other?

Even though the two surfaces are sliding past each other, there can still be a frictional force between the surfaces, but this sliding friction we call a kinetic frictional force.

## What is the force between two moving objects touching each other?

Friction is the force that works against the motion between two objects that are touching each other. Friction might stop motion from starting, or it might slow the object’s motion that is already happening.

## What is a force that occurs between two surfaces called?

Frictional force Frictional force is a type of contact force. It starts to act whenever two surfaces are in contact with each other or move or tend to move over one another. It is the force that resists motion when two objects are in contact.
