Test Questions Two tugboats are moving a barge. Tugboat A exerts a force of 3000 newtons on the barge. Tugboat B exerts a force of 5000 newtons in the same direction. What is the combined force on the barge? 8000 newtons 4000 newtons 2000 newtons None of the above If two men were arm wrestling and the first man was using 15 newtons, while the other was using 10 newtons, who would win? A. Neither B. First Man C. The one using 10 newtons D. The information given is not enough to answer the question What is net force? The amount of matter in an object. How much work is being done? The total force acted upon an object. How heavy the object is. Which direction will a rope go towards to when an unbalanced force is acted upon it? Nowhere Towards the unbalanced force Right Left

AP Newton's Laws Review Sheet Newton's First Law (AKA Newton's Law of Inertia) ?Consider an object with no force acting on it. If it is at rest, it will remain at rest; if it is moving, it will continue to move in a straight line at a constant speed? 5 Everyday Forces Weight Fg = mg (direction is always down) Normal Force Fn (direction is always perpendicular to the surface Friction Ff = ?Fn (direction always opposes direction of motion) Applied Force FA (pushing or pulling) Tension FT (direction is always along the string or rope; tensions are equal on either side of a massless, frictionless pulley)

AP Kinematics Review Sheet Basic Terms: Position ? Location (sometimes in x and y coordinates) Displacement ? Distance and direction from initial position Speed ? Rate of change of displacement; magnitude only Velocity ? Rate of change of displacement; direction and magnitude; v = ?x/?t Acceleration ? Rate of change of velocity; direction and magnitude; a = ?v/?t For graphs of position versus time, velocity versus time, and acceleration versus time: Velocity is the slope of a position versus time graph Average velocity ? only use the first and last points Instantaneous velocity ? use the slope of the tangent line to the curve *The area under a velocity vs time graph equals distance acceleration is the slope of a velocity versus time graph

KEY CONCEPTS KINEMATICS 1. MOTION IN ONE DIMENSION Kinematics is the study of how objects move, and the formal description of that motion. Kinematics doesn?t concern the forces that cause the motion or the masses involved. Instead it addresses such questions as: How far does an object move? How long does it take? How fast is it moving? The relevant quantities in kinematics are displacement, time, velocity, and acceleration. Displacement is related to the distance an object moves, displacement measures the change in position and is written as ?x. Time is denoted either as t, a specific moment in time, or as ?t, the time interval over which some event occurs. Velocity refers to how fast an object is moving and in what direction. The magnitude of
