Key Terms

Review the following key terms (Glossary chapters 4 and 5):

acceleration

the rate at which an object’s velocity changes over a period of time

centre of mass

the point where the entire mass of an object can be thought to be concentrated

friction

a force that opposes relative motion or attempts at motion between systems in contact

kinetic friction

a force that opposes the motion of two systems that are in contact and moving relative to one another

Newton’s Laws of motion

are basic laws of classical mechanics that describe the relationship between the motion of an object and forces acting on it

Newton’s universal law of gravitation

every particle in the universe attracts every other particle with a force along a line joining them; the force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them

static friction

a force that opposes the motion of two systems that are in contact and are not moving relative to one another
