Select ALL the statements that best reflect what is occurring as the rock moves up the hill

You get to ride a thriller water slide (as depicted below). Each letter represents a location along the ride. Between which two points would you predict the smallest change in energy?

Which of the following represents the position in which the roller coaster has the maximum potential energy?

Which point on the pendulum's swing represents the minimum potential energy?

A group of students is exploring how different variables affect the kinetic energy of a cart. They set up four different experiments. One end of the ramp rests on 1 to 3 blocks and the cart carries a load of one to three 20g marbles. For each test, they release the cart at the top of the ramp and measure its speed at the bottom of the ramp.

Which experiment(s) best explores the relationship between mass and kinetic energy? (remember you can only change 1 thing) **Look at the marbles**

The data table below shows the speed of each car recorded at each second. Based on the data, which car(s) traveled at a constant speed? **Select more than one**

A roller coaster is traveling 1 m/s at the top of the track. At the bottom of the track, 3 seconds later, it is traveling 36 m/s. What is the average acceleration?

Alexis walked 1.5 km to her house in 0.5 hours. What is Alexis' speed?

The Law of Inertia states that an object in motion will stay in motion, and an object at rest will stay at rest unless acted upon by an unbalanced force. Which law is this describing?

Student's in Ms. Sawyer's class built balloon cars. As the gas in the balloon is released, the car moves in the opposite direction. The bigger the balloon initially, the farther the car moves. This balloon car is a good model of Newton's -

A satellite orbiting above the earth (shown below) needs no power source to keep orbiting the earth. The best explanation for this involves the law of inertia. Simply

put the law of inertia states -

This graph shows the position over time for four runners. You will notice that runner A and D each started ahead of runner B and C. Which runner had the fastest average speed? **Fastest increases the quickest**

A motor boat is traveling 10 m/s on a sunny calm day. The driver turns off the engine. Apply Newton’s first law to explain what happens to the boat as it glides through the water.

A pair of scissors (shown below) is a first class lever. The fulcrum is between the handle and the blades. The blades contain two simple machines back to back: they are also

A car travels 10 miles East in 30 minutes. What is the car's velocity in miles per hour? S= d/t

A force is best described as a push or a -

During science class, Ben and Dylan had to set up a demonstration to model one of Newton's laws. When Ben hit the index card with his finger, the penny fell into the cup (it was at rest). What does the students' demonstration illustrate?

Freight trains are a common sight, traveling railways all across this country, delivering loads. If you’ve ever seen one, you probably know that they are large and heavy machines.

That is why, once a freight train gets going, it is hard to stop. However, even if no brakes are applied even the biggest train will eventually come to a stop due to a force at work between the rails and the wheels of the train. What is that force?

Why would Farmer Bob decide to use a compound pulley to raise a box up to the top of his barn?

A shovel can be called a compound machine because it can be used as a...(select all that are right)

Sara and Sam went for a two-hour drive. According to the graph, between .75 hours and 1.25 hours into their trip, they -

Calculate the amount of work done if you use a 100N force to push a 50kg box 5m across the kitchen floor.

Calculate the force needed to cause a 6 kg bowling ball to accelerate 20 m/s2.

In which situation is there no work being done?

Suppose a rollerblade racer finished a 132 meter race in 18 seconds. What is the average speed of the racer?

Calculate the net force and select the description that describes the movement of the vase.

Calculate the net force and direction the object will move.

The data table below shows the speed of each car recorded at each second. Based on the data, which car(s) accelerated?
