Practice Problems on white board. Review / project time. Friction. Friction is a force that opposes the motion, or tendency of motion, of an object.. Friction is caused . mostly by . the . electromagnetic . interactions of particles within molecules at the surfaces of objects in contact. While these interactions can be rather complex, their combined effects can be reasonably approximated with a decent amount of consistency.. Friction. Friction is a force that opposes the motion, or tendency of motion, of an object.. Friction is primarily caused by the chemical bonding of molecules at the surfaces of objects in contact (intermolecular forces which are electrical in nature). 2. Objectives. .
