Newton's Laws	Centripetal Forces	Friction	Momentum and Impulse
100 A tendency to do nothing or remain unchanged Inertia	100 Which direction is the acceleration vector pointing? Center	100 What is static friction? The amount of friction that opposes the initial motion of an object.	100 What is momentum? Mass in motion
200 Which law can also be stated as The Law of Inertia Newton's First Law of Motion	200 Which direction is the velocity vector pointing? Tangent to the curve	200 What is the equation for finding kinetic friction? Ff=uFn	200 If the force acting on an object is doubled how does this affect the impulse? Doubled
300 Which law states: "when an unbalanced force acts on an object, the object will be accelerated" Newton's Second Law of Motion	300 What is the tension in a string used to twirl a 0.3 kg ball at a speed of 2 m/s in a circle of 1 meter radius? 1.2 N	300 A car tire sits on a dry highway. It has a weight of 500N. What frictional force will be produced as the object begins to move? 3,350 N
400 An object of mass,10 kg, is accelerated at a rate of 26 m/s/s. What force is acting on the object? 260 N	400 Calculate the centripetal force acting on a 925 kg car as it rounds an unbanked curve with a radius of 75 m at a speed of 22 m/s 5, 960 N	400 An unbalanced force acts on an object with a magnitude of 75N. The frictional force works against the 5kg object, that is accelerating at a rate of 2 m/s/s. What is the net force? 10 N
500 If the force of gravity acting of an object is 98 N, there will be a 98 N force in the opposite direction. Which law makes this possible? Newton's Third Law	500 An car (m=2000 kg) moves in a circle whose radius is 200 m. If the force acting on the car is 3600 N, what is its speed? 18.9 m/s
