aFriction is the force that opposes motion but inertia is the reluctance of anobject to change its state of rest or motion. [B1]Friction is dependent on weight but inertia is dependent on mass. [B1|bWeight depends on gravitational field strength, thus it is not constanteverywhere.Weight is...
“Friction is the force that opposes motion between two surfaces in contact with each other”(Bird). The best example in ballet regarding friction is pointe shoes. Because they are made of satin and have little surface area, they are perfect for doing more turns and faster. Fouetté turns, ...
Friction Friction is a force that opposes motion between two surfaces that are in contact Frictions occurs because surfaces are covered with microscopic. Friction. How does friction affect motion? How does friction affect motion? Section 1-2 Friction and Gravity....
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:1

Friction is the force that opposes the relative motion of solid bodies and fluids and can present itself in both dry and fluid forms. For the case of fluid friction, a body moving with speed U with respect to the surrounding fluid generally may experience three primary types of drag: Stokes...
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...
The force of friction is the force that opposes the movement of an object along a surface. This force always acts against an applied force, and the force that resists the movement of an object.Answer and Explanation: Become a member and unlock all Study Answers Start today. Try it now ...
Friction is a force that opposes the motion of an object when it is in contact with a surface. At the microscopic level, it is caused by surface roughness of the materials in contact and intermolecular interactions. But one can overcome this force by application of an external force that is...
