Public Quiz: Unit 2 : Energy and Its Applications (Science) - Preparatory 1

Question of

Question 1

If the speed of a moving object is doubled while its mass remains constant, how is its kinetic energy affected?

Question 2

When experimenting on how height affects the depth of a marble's crater in sand, which factor should be a controlled variable?

Question 3

The generation of electricity from the High Dam exemplifies the transformation of potential energy into electrical energy through an intermediate kinetic energy stage.

Question 4

What two factors primarily determine the potential energy of an object above the ground?

Question 5

The potential energy of an object primarily depends on which two factors?

Question 6

Which variable is measured or observed to see how it responds to changes made in another variable during a scientific experiment?

Question 7

What is the fundamental ability to do work?

Question 8

For a freely falling object, its mechanical energy is equal to its potential energy at its maximum height.

Question 9

Which formula correctly represents the kinetic energy of an object?

Question 10

At which position does a freely swinging pendulum have its maximum kinetic energy?

Question 11

Speed can only be measured in meters per second (m/s).

Question 12

The mechanical energy of an object increases if its potential energy decreases and its kinetic energy increases by the same amount.

Question 13

What is potential energy?

Question 14

Kinetic energy is estimated by the amount of work done during the motion of an object.

Question 15

Controlled variables are those that are intentionally changed by the experimenter to observe an effect.
