4 (a) State two differences between friction and inertia.Friction is the force that opposes motion but inerti a is the reluctance of an object to change its state of rest or motion. [B1]Friction is dependent on weight but inerti a is dependent on mass. [B1](b) Weight is the force of...

Friction is the force that opposes the motion when two surfaces in contact move or tend to move with respect to each other. It always acts opposite to the direction of motion, thus it is an opposing force.Answer and Explanation: There are different types of friction, such as- static fricti...
Friction is the force that opposes the relative motion or tendency of such motion of two surfaces in contact. The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. Friction results from the two surfaces being pressed together...
What are the 4 main types of 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. ...
Before delving into the functions of bearings, it’s important to grasp the concept of friction and its implications in mechanical systems.Friction is the force that opposes motionbetween two surfaces in contact, resulting in energy loss, heat generation, and wear. In rotational applications, fricti...
Kinetic friction, abbreviated as fkfk, also called dynamic friction or sliding friction, is the force that opposes the relative motion of two surfaces that are moving with respect to each other. When an object is in motion, the irregularities on the surfaces in contact slide past each other, ...
Friction is a force that opposes the relative motion or tendency of motion between two surfaces in contact. Think of it as the 'stickiness' between things when they rub against each other. Let’s say you’re trying to slide a book to a friend seated across the table. The table's surf...
The frictional force on each body is in an opposite direcrion to the motion of the other body. Since no surface is perfectly smooth, all having at least a minute roughness, there will always be friction, no matter how small the friction. Friction is a force that opposes the relative ...
Kinetic friction is the force that opposes the movement of two surfaces in contact with each other, while static friction is the force that prevents two surfaces from moving relative to each other. How is kinetic friction measured? Kinetic friction is typically measured by the coefficient of frict...
