- Hydroelectric energy can be found throughout earth? Is this a pro or con? Con D Pro
- Student Exploration Fan Cart Physics Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: acceleration ,force, friction, mass, newton , Newton's first law, Newton's second law, Newton's third law, velocity Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. Imagine a horse pulling a cart. What would happen to the speed of the cart if several bags of cement were added to the cart? square 2. Suppose several more horses were hitched up to the same cart. How would this affect the speed of the cart?
- 5. An FM radio station broadcasts electromagnetic waves at a frequency of 94.5MHz (equal to 94,500,000Hz These radio waves have a wavelength of 3.17 meters. What is the speed of the waves? square square square square
- A helicopter's speed increases from 25m/sec to 60m/sec in 5 seconds. What is the acceleration of this helicopter? Do not include units with your answer.
- 1) What is meant by relative motion? 2) What is a frame of reference? 3) When you are asked what the motion of an object is relative to a frame of reference, what velocity does an observer in that frame of reference imagine that s/he has? 4) Tim is walking down the aisle of a speeding bus and tosses a coin into the air. Matthew is standing on the sidewalk outside. a) Draw the trajectory of the coin from Tim's frame of reference b) Draw the trajectory of the coin from Matthew's frame of reference. 5) Tara is a pilot that is going to drop a package on an enemy storage depot. With a camera mounted under the plane, she watches the package drop Annie is an observer on the ground who also watches the package drop. Assume air resistance is small. a) Draw the trajectory of the package from Tara's frame of reference. b) Draw the trajectory of the package from Annie's frame of reference. 6) An old-fashioned physics dilemma used to be- if a sailor in the crow's nest (a place way up high in the rigging) of a sailing ship that was moving at constant speed dropped a tool onto the deck of the ship, would it land directly beneath where he dropped it or since the ship was moving, would it land further back? Explain your answer.
