Motion and Momentum - $100 What formula do you use to find velocity? What about acceleration? Speed: Distance Time Acceleration: Vf- Vi T

Motion and Momentum - $200 What type of movement is shown in the table? Constant speed

Motion and Momentum - $300 As the ball is being thrown up, what is the acceleration acting on the ball? How does the speed differ from the first arrow to the last arrow? Gravity, going down They are the same speed

Motion and Momentum - $400 If a 2kg car starts at rest and after 10 seconds has a velocity of 20 m/s, what was the cars change in momentum? Change in Momentum = MV Change in Momentum = 2kg X (20 m/s – 0 m/s) Change in Momentum = 2 kg x 20 m/s Change in Momentum = 40 kg m/s

Motion and Momentum - $500 If a 3 kg car is moving at 15 m/s and collides with a 5kg car at rest. If this is an inelastic collision, what would the final velocity be? (M1xV1) + (M2xM2) = MV (3)(15) + (5)(0) = 8(V) 45 + 0 = 8(V) 45 = 8(V) V = 5.625 m/s

Graphs - $100 Using the graph to the right, which jogger has the greater average speed? The Red Jogger

Graphs - $200 What kind motion does the car have? Constant speed

Graphs - $300 Using the Position vs. Time graph, determine the speed of the object between 1s and 8s. V = D/T V = 120 m / 8 sec V = 15 m/s

Graphs - $400 Explain how you find velocity on a distance- time graph. Explain how you find acceleration on a velocity- time graph. Distance-time: Find the distance traveled and divide by the time it took. Velocity-time: Vf – Vi and divide by the time it took.

Graphs - $500 Using the velocity time graph, determine which object has a change in momentum of 1500 kg m/s. Each object has a mass of 100 kg   20 15 10 5 2 4 6 8 Object B

Energy and Work - $100 The diagram to the left shows a roller coaster and its path. Which point is where the roller coaster will have the lowest potential energy? Lowest potential energy at point 3

Energy and Work - $200 What hitting a hockey puck, the player wants to follow through in order to increase what? The final velocity of the hockey puck

Energy and Work - $300 How much work is done when a 3 kg person walks up a 4 meter flight of stairs. (hint: You are given mass, not force!) W=mgh W=(3)(10)(4) W=120 J

Energy and Work - $400 Describe gravitational potential energy, kinetic energy, and mechanical energy. Gravitation potential energy is due to an objects position. PE = mgh Kinetic energy is energy in motion. KE = M (V2) 2 Mechanical energy is PE + KE. ME = mgh + M (V2)

Energy and Work - $500 Acceleration = Force / Mass 10 kg 20 N 70 N Acceleration = Force / Mass Acceleration = 50 N / 10 kg Acceleration = 5 m/s2

Newton’s Laws - $100 According to Newton’s second law, how is mass, acceleration, and force related. The more the mass an object has, the less it will accelerate. The more force you apply to an object, the more it will accelerate.

Newton’s Laws - $200 What happens when unbalanced forces act on an object? It accelerates

Newton’s Laws - $300 A car has a mass of 10,000 kg and is accelerating at 3 m/s/s. What is the force acting on the bus? F = Mass X Acceleration F = 10,000 kg X 3m/s/s F = 30,000 Newtons

Newton’s Laws - $400 If a ball is pushed with a force, why will it continue to move at that rate? Inertia is the resistance to change in motion and a ball continues to move even after there is no force because once a force is applied, that ball will have inertia and continue to travel.

Newton’s Laws - $500 State Newton’s 3rd Law Give two example of Newton’s 3rd Law in the following scenario: You are walking to school with your book bag on. For every action there is an opposite and equal reaction. You pushing on the ground and the ground pushing on you. Your book bag pushing on you and you pushing on your book bag.

Waves - $100 What does this picture show? Diffraction

Waves - $200 Which of the following material would transmit sound the fastest; Water, solid, or air? Solid

Waves - $300 Wave A has an amplitude of 7 meters and wave B has an amplitude of 8 meters. What would be the resulting amplitude when there wave interfered? 2 meters

Waves - $400 Describe how light rays reflect off a concave mirror. Parallel to P then through F Through F then parallel to P Through C

Waves - $500 Describe the Doppler effect and give an example of it. A change in sound frequency (pitch) caused by the motion of the sound source, the listener, or both. When you are standing on the side of the road and a siren passes you.
