What is the mechanical energy of an object?

the sum of all kinetic energy and all potential energy

the sum of all types of kinetic energy

the sum of all types of potential energy

the difference between the kinetic energy and the potential energy

A high-speed collision between two vehicles causes more damage than a low-speed collision. What is the reason for this?

Vehicles traveling at a high speed have more kinetic energy than vehicles traveling at lower speeds.

Vehicles traveling at a high speed have no potential energy.

Vehicles traveling at a low speed have no potential energy.

Vehicles traveling at a low speed have more kinetic energy than vehicles traveling at higher speeds.

Energy can be transformed from one type to another. In which of the following situations is kinetic energy transformed into potential energy?

When a ball is thrown straight up into the air

When a boulder rolls down a mountain

When a water tank ruptures and water flows out

When a tree branch falls toward the ground

Which statement would correctly describe the energy of the ball as it travels along the path?

The ball has the most kinetic energy at point C.

The ball has the most potential energy at point D.

The ball has the least potential energy at point A.

The ball has the least kinetic energy at point D.

According to the law of conservation of energy, what happened to the energy of the ball in the Illustration below?

Potential energy was transformed into kinetic energy.

The amount of total energy in the ball increased.

Both the potential energy and the kinetic energy remained unchanged.

The amount of total energy in the ball decreased.

Experimental results must be replicable to be generally accepted as true. One reason replication is important is because it can reduce or eliminate bias by an individual scientist. What is a replicable experiment?

when different scientists use the same procedures to obtain the same results

when the same scientist repeats the same procedure and obtain different results

when the same scientist repeats the same procedures and obtains the same results

when different scientists use the same procedures and obtain different results

The graph below plots the distance in kilometers traveled by an object over time in hours. What can you conclude from this graph?

The speed of the moving object remains constant.

The speed of the moving object increases over time.

The speed of the moving object decreases over time.

The speed of the moving object first increases and then decreases.

Look closely at the graph below. What can you conclude about the motion of the object?.

The object is returning to its original position.

The speed of the object is slowly increasing at a constant speed.

The motion of the object is decreasing at a constant speed.

The object is maintaining its direction of motion.

When conducting an experiment, a chemist added "a tiny bit of glucose and a sprinkle of calcium powder" to the reaction mixture. What is wrong with using this type of measurement?

A bit and a sprinkle cannot be replicated by other experimenters.

A bit and a sprinkle were too little of each chemical to be used in the reaction.

A bit and a sprinkle were too much of each chemical to be used in the reaction.

A bit and a sprinkle of these chemicals do not mix completely to get the desired results.

Downhill snow skiing shows the relationship between kinetic and potential energy. What happens to the energy transformation as the person skis down the hill?

As the skier begins to go down the hill, potential energy transforms into kinetic energy.

As the skier begins to go down the hill, kinetic energy transforms into potential energy.

The skier uses her ski poles to create more kinetic energy.

There is no change; potential and kinetic energy remain the same.
