# What is the force that opposes motion of one surface across another?

## What is the force that opposes motion of one surface across another?

Friction
Friction is a force that opposes motion. It is present whenever two surfaces rub over each other, such as when you rub your hands together, or when you apply the brakes on a bike or in a car.

What is a force that opposes the motion of objects that move through the air?

The air resistance is a special type of frictional force that acts upon objects as they travel through the air. The force of air resistance is often observed to oppose the motion of an object.

What is the type of force that opposes the force of weight on a horizontal surface?

Friction is a force that opposes two objects sliding against each other, and is a contact force like the normal force. While the normal force acts perpendicular to the flat surface, friction acts in a direction along the flat surface of an object.

### What outside force opposes the direction of motion on the surface of a table?

Friction is a force and affects motion: Friction acts on materials that are in contact with each other. It always acts in a direction to oppose motion. Caused mainly by irregularities in the two surfaces.

What kind of force opposes the motion of the paper?

friction
The force that acts against your pushing force is called friction. is a force that resists the motion between two surfaces in contact. When you try to slide two surfaces across each other, the force of friction resists the sliding motion.

Is the force that opposes relative motion of surfaces in contact?

Friction is a force that opposes relative motion between surfaces in contact. One of the simpler characteristics of friction is that it is parallel to the contact surface between surfaces and always in a direction that opposes motion or attempted motion of the systems relative to each other.

#### What is a force that resist motion?

friction: The resistance an object meets when moving over a surface or through a gas or liquid; it is the force that resists the motion of two surfaces that are touching each other. It is also the force of attraction between any two objects.

What is a force that opposes the motion of objects in free fall?

Free fall is the motion of a body where its weight is the only force acting on an object. Air resistance opposes the motion of an object through the air, while friction opposes motion between objects and the medium through which they are traveling.

What force is always directed opposite to the motion of an object?

Friction is directed opposite the direction of relative motion or the intended direction of motion of either of the surfaces. The force exerted by an object being pulled upon from opposite ends like a string, rope, cable, chain, etc. Tension is directed along the axis of the object.

## What is frictional force example?

The force of friction is always exerted in a direction that opposes movement (for kinetic friction) or potential movement (for static friction) between the two surfaces. For example, a curling stone sliding along the ice experiences a kinetic force slowing it down.

What is the direction of frictional force against a motional object *?

The direction of frictional force is always opposite to the direction of motion. Friction always tends to oppose the applied force. Therefore, the correct option is (B) Opposite to the direction of motion.

What type of friction opposes the motion of a moving object?

static friction
Sliding friction is stronger than static friction. Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces.

### What is the force that opposes motion between two objects?

Friction is the force that opposes motion between two objects. What is the force that opposes the motion of two touching surfaces? the force that opposes the motion of two touching surfaces is velocity.

Is there always something that opposes motion?

Depending on the surroundings, there is almost always something that opposes motion even if it doesn’t seem like there is any friction present. i.e. hockey puck on ice may seem like it has no friction but that is not true! Q: What is the force that always opposes motion?

Does friction always oppose the motion of an object?

Though it is not always the case, the friction force often opposes the motion of an object. For example, if a book slides across the surface of a desk, then the desk exerts a friction force in the opposite direction of its motion.

#### What is the single force that is a source of confusion?

A few further comments should be added about the single force that is a source of much confusion to many students of physics – the force of gravity. As mentioned above, the force of gravity acting upon an object is sometimes referred to as the weight of the object. Many students of physics confuse weight with mass.
