Question #1 : Which of the following is an example of a vector quantity? *

1 point

Distance

Mass

Displacement

Time

Question #2 : Which statement is true about the type of motion represented by the position-time graph shown below? *

1 point

The object is moving eastward at a constant velocity.

The object is stationary at a location to the east of the reference position.

The object is stationary at a location to the west of the reference position.

The object is moving westward at a constant velocity

Question #3 : Which of the following velocity-time graphs represents the motion of a ball thrown vertically upward (assume the ball has left the throwers hand)? *

1 point

Question #4 : How do you determine velocity from a position–time graph? *

1 point

Read information directly from the graph

Find the area under the graph

Take the slope

none of the above

Question #5 : If you launch a ball horizontally out of a window at the same time you drop a ball, which of the following things will happen? *

1 point

The ball that was dropped will hit the ground first

Both balls will hit the ground at the same time

The ball that was launched horizontally will hit the ground first

The ball launched horizontally will slow down.

Question #6 : What is the net force acting on the following object: *

1 point

72 N [E]

54 N [W]

18 N [N]

18 N [E]

Question #7 : Which of the following is a measure of the force of gravity acting on an object? *

1 point

Weight

Inertia

Volume

Mass

Question #8 : Which of the following is an example of a non-renewable energy resource? *

1 point

Geothermal

Hydroelectricity

Nuclear Energy

Solar Energy

Question #9 : In which of the following examples is work being done? *

1 point

A child kicks a soccer ball across a field.

A man pushes against a large crate that will not move.

A 0.5kg laptop sits on a student's desk 0.8m above the ground.

all of above

Question #10: Which statement(s) about the amount of work done on an object is (are) true? *

1 point

If the force on an object and the object’s displacement are in the same direction, the amount of work is a negative value.

If a force acts on an object in a direction opposite the object’s displacement, the amount of work is a positive value.

If the force on an object and the object’s displacement are perpendicular, no work is done.

all of the above

Question #11: Which statement about warmth and coldness is true? *

1 point

Thermal energy is the total kinetic energy possessed by the particles of a substance.

Temperature is a measure of the total kinetic energy of the particles in a substance.

The kinetic molecular theory states that as particles of matter gain kinetic energy, they move faster and the temperature of the substance decreases.

Scientists typically use the Fahrenheit temperature scale.

Question #12: How many changes of state are shown in this heating graph? *

1 point

Question #13: Which of the following accurately describes what happens to a wave after a free-end reflection? *

1 point

A crest will be reflected as a trough but with a smaller amplitude.

A crest will be reflected as a crest but with a smaller amplitude.

A crest will be reflected as a trough with the same amplitude.

A crest will be reflected as a crest with the same amplitude.

Question #14: What will happen as the following two waves interfere? *

1 point

The waves will cancel each other out and stop travelling.

The amplitudes will add and the resulting wave will have a larger amplitude. The waves will continue moving afterward.

The amplitudes will add and the resulting wave will have a larger amplitude and this resulting wave will move to the left.

The amplitudes will subtract and the resulting wave will be smaller in amplitude. The waves will continue moving afterward.

Question #15: Which of the following devices is used to measure the potential difference across a load? *

1 point

Voltmeter

Ohmmeter

Ammeter

Spectrometer

Question #16: Current is measured as which of the following? *
