Summarizing questions: complete under your notes and bring to class.

 

1.     Explain how acceleration is different from speed and velocity.

2.    Explain how acceleration, velocity, and time are related.

3.    Consider a situation where you are playing air hockey with a friend. The table shoots small streams of air upward to keep the puck afloat and to minimize friction. When you barely tap the puck forward, what happened?

4.    When a bus comes to a sudden stop to avoid hitting a dog, it slows from 9.00 m/s to stop in 1.50 seconds. Find the acceleration of the bus.

5.    Explain how a car could accelerate if its speed is a constant 65 km/h.

6. Tommy was walking at a rate of 4 mph at noon and at 12:30 pm he was walking at a brisk rate of 6 mph. Two hours later Tommy was walking at a leisurely rate of 2mph. What was Tommy's acceleration between noon and 12:30 pm? Show Given and Work

7. An object is going 22 m/s and is 3 kg. Find momentum. Show Given and Work

8. Two astronauts push off of each other in space. The 80 kg astronaut ends up going 10 m/s. The other one ends up going 8 m/s. What is the mass of the other astronaut? Show Given and Work

9. Using the Law of Conservation of Momentum, solve the following: A 40 kg boy on a skateboard throws a 2 kg, 20 m/s to the left. Find how fast the boy is going afterward.

10. If 2 football players are running at the same velocity towards an opponent.  Player 1 weighed 170 lbs, player 2 weighed 250 lbs.  Who is going to move the opponent farther?  Why?

Motion HOT Question

Question- asking Higher Order Thinking (HOT) questions; use the following as your guide:
1. A question that you are still confused about (be specific, include which part of the video, etc)
2. A question that connects the videos together (i.e. asking about the relationship between the content)
3. A question you think you know the answer to, but you want to challenge your classmates with
