Unit 2 Objectives: Forces and Laws of Motion
... 4. What is the difference between the weight of an object and the mass of an object? Mass is amount of “stuff” in an object, weight is how hard earth pulls object 5. Explain what causes friction. Two surfaces in contact rub against each other How could one reduce the friction an object experiences? ...

... In the following questions, you should think first about the type of motion – is the object stationary (at rest) or traveling at a constant velocity (uniform speed in a straight line), or is the object undergoing an acceleration? This will tell you whether Newton’s First Law or Newton’s Second Law a ...

Circular Motion and Gravity
... • In circular motion, if an acceleration causes a change in speed, it is called tangential acceleration. • To understand the difference between centripetal and tangential acceleration, consider a car traveling in a circular track. – Because the car is moving in a circle, the car has a centripetal co ...
