Practice AP Physics C: Mechanics Work, Energy, and Energy Resources in the app →The study of motion without considering its causes is:To describe the position of a passenger walking inside an airplane, the most convenient reference frame is:Displacement is defined as the change in an object's:The SI unit for displacement is the:A professor moves from x = 1.5 m to x = 3.5 m. Her displacement is:A professor paces 150 m during a lecture but ends 2.0 m right of her start. Her distance traveled is:A cyclist rides 3 km west then 2 km east. The magnitude of the displacement is:A quantity with both magnitude and direction, such as a velocity of 90 km/h east, is a:A 20 degree temperature, a 1.8 m height and a 2.0 m distance are all:Which quantity is never represented by an arrow?Once you assign a positive direction in a problem, you:The SI unit for time is the:A lecture runs from 11:00 to 11:50 AM. The elapsed time is:Average velocity is displacement divided by:An airplane passenger moves -4 m in 5 seconds. His average velocity is:A car's speedometer shows the magnitude of its:You drive to a store and back in half an hour, 6 km total. Your average speed is 12 km/h and your average veloAverage acceleration is the rate at which which quantity changes?A car turning a corner at constant speed is:When an object slows down, its acceleration opposite to its motion is called:A racehorse accelerates from rest to 15.0 m/s west in 1.80 s. Its average acceleration magnitude is:The train slows from 30.0 km/h to a stop in 8.00 s. Its acceleration is about:Linear momentum is the product of a system's mass and its:The SI unit for momentum is:A 110 kg football player runs at 8.00 m/s. His momentum is:A 0.410 kg football thrown at 25.0 m/s has momentum of about:Although the ball is faster, the player has far more momentum because of his much greater:Momentum form of Newton's second law is useful for systems whose mass changes, such as:Venus Williams's 2007 serve reached a ball speed of:The average force on the 0.057 kg ball in contact with the racquet for 5.0 ms was about:The quantity average net force multiplied by the time it acts is called:Airbags reduce injury by making the stopping force act over a:Deaths in car racing fell sharply when rigid frames were replaced by parts that:Rolling on the ground after a jump protects your bones by extending the:On a force-versus-time graph, the area under the curve equals the:When a football player hits a goalpost, momentum is still conserved because the Earth also:An isolated system is one for which the net external force is:Squids propel themselves like jellyfish and typically move at:A collision that conserves internal kinetic energy is called:Truly elastic collisions are achieved only with:A 0.500 kg object at 4.00 m/s hits a 3.50 kg object at rest elastically. The small object:A collision in which the objects stick together is called:A 70.0 kg goalie at rest catches a 0.150 kg puck moving at 35.0 m/s. His recoil velocity is:Why does a heavier tennis racquet have the advantage? In a collision what is conserved is:
