A sled maintains a speed of 80 mph as it rounds a curve on the track. Is the sled accelerating?

Yes, because it is changing direction

No, because the speed is constant

Yes, because it is slowing down

No, because it is on a straight path

Which object would require the most force to begin moving? Provide an explanation.

a. Bowling Ball requires more force because mass and inertia are directly proportional

b. Beach Ball requiires more force because mass and inertia are indirectly proportional

c. Volleyball requires more force because mass and inertia are directly proportional

d. Tennis Ball requries more force because mass and inertia are indirectly proportional

Several elves conducted an experiment to determine the relationship between force and acceleration. They pushed the same small cart with various levels of force and measured the acceleration of the cart as it moved through a track. Based on the data below, what do you predict will happen to the cart’s acceleration during Trial #3? Provide an appropriate explanation.

c. Prediction: Acceleration decreases to 2 m/s². Explanation: Force and acceleration are directly proportional.

a. Prediction: Acceleration increases to 72 m/s². Explanation: Force and acceleration are inversely proportional.

b. Prediction: Acceleration decreases to 6 m/s². Explanation: Force is equal to acceleration.

d. Prediction: Acceleration must be measured separately for each new trial. Explanation: Force does not change acceleration in a predictable manner.

When a Civil War era cannon is fired, the force of the gas produced by exploding powder propels the cannonball forward at a high speed. According to Newton’s Third Law,

c. The cannon itself moves forward as well because of momentum

d. The cannon itself moves forward with the inertia of the cannonball

Slamming on the brakes in a moving car makes a passenger move forward against his or her seat belt because

c. The passenger's inertia keeps them moving forward.

d. The brakes apply force to the passenger.

Frosty dropped three different objects down a 5.0 m vacuum chamber. Frosty then determined the force on each object given its mass and created the table shown. What relationship can be determined based on an analysis of the data?

c. All three objects have the same downward acceleration regardless of mass.

a. Each object has a final velocity that is proportional to its mass.

b. Each object has an acceleration that is proportional to its mass.

d. All three objects have the same amount of inertia regardless of mass.

An Astronaut on the moon drops a feather and a rock from the same height. They reach the ground at the same time. Why does this happen on the moon but NOT on Earth?

There is no air resistance on the moon

The moon has a stronger gravitational pull

The feather is heavier on the moon

The rock is lighter on the moon

Which of the following is not a description of weight?

stays the same in all locations

Which best describes the function of a lever?

using a small force over a long distance to move a large object a short distance

using a small force over a short distance to move a large object over a short distance

using a large force over a long distance to move a small object over a short distance

using a large force over a short distance to move a small object over a long distance

Which of these is an example of work being done on an object?

holding a door shut on a windy day so it doesn’t blow open

holding a heavy piece of wood at a construction site

trying to push a car that doesn’t move out of deep snow

Which of the following best describes the energy conversions that take place when a match is lit?

Chemical energy is converted into light and heat.

Chemical energy is converted to electrical energy.

Kinetic energy is converted into light and sound.

According to the Law of Conservation of Energy, the following are equal:

Potential energy at W and Potential energy at Y

Kinetic energy at X and Kinetic energy at Z

Potential energy at W and Kinetic energy at X

Kinetic energy is equal to Potential energy at each point.

Which of the following best describes the energy transformation that takes place when a reindeer runs?

Chemical energy is converted to kinetic energy.

Kinetic energy is converted to potential energy.

Heat energy is converted to chemical energy.

Heat energy is converted to potential energy.

The diagram shows how a power plant produces electrical energy. Choose the step in which mechanical energy is transformed into electrical energy.

The turbine causes an axle covered with magnets to spin in the generator. The axle is surrounded by wires, so the spinning action causes electricity to be produced.

The steam is cooled to produce water.

A fuel, such as coal or oil, is burned to heat air. The hot air then heats water to form steam.

Heat transferred by conduction will travel best through

Solids because the particles are close to one another.

Liquids because the particles are free to move from one location to a different location.

Gases because the particles are already moving fast and have a large amount of kinetic energy.

A vacuum because there are no particles to get in the way of the electromagnetic waves of heat moving around.

The process of convection transfers heat when warm fluids move in currents. Which of the following correctly describes the movement of fluids in convection currents?

Warm particles rise, and cool particles fall.

Cold flows from cooler areas to warmer areas.

Heat flows from cooler areas to warmer areas.

Cool particles rise, and warm particles fall.

On the diagram above, what is happening to the temperature and heat energy between points 3 and 4, going to the right?

Temperature is staying constant while heat energy is increasing.

Both temperature and heat energy are increasing.

Temperature is staying constant while heat energy is constant.

Temperature is increasing while heat energy is decreasing.
