The box would be easier to move if the surface of the ramp was smoother because there would be less -
distance to push the box
mass in the box
friction opposing the box
gravity pulling on the box
These three different objects produce the same type of energy.
WHAT IS THE TYPE OF ENERGY PRODUCED BY THESE OBJECTS?
light energy
thermal energy
sound energy
electrical energy
A student placed his marble game above a stereo speaker. When he turned the speaker on, the marbles shook and some fell to the floor.
WHICH OF THE FOLLOWING STATEMENTS BEST EXPLAINS THE MOTION OF THE MARBLES?
magnetic energy attracted the marbles
sound waves cause the marbles to vibrate
electricity pushed the marbles
heat caused the marbles to move
Three different objects that use the same source of energy are shown.
WHAT IS THE ENERGY SOURCE FOR THESE OBJECTS?
Mechanical energy
Light energy
Sound energy
Electrical energy
A student was standing outside at recess and noticed his shadow.

A student uses a spring scale to pull a 50-gram block horizontally across a wood desk. Then the student pulls the block the same distance across surfaces of carpet, sandpaper, and glass. Which question is this investigation most likely designed to answer? (5.6D)
How do block of different sizes react to force?
How do different surfaces affect the amount of force needed to move a block?
How do blocks affect spring scales?
How does the mass of a block change when it is pulled across a desk?
A student observes that the craters on the moon are different sizes. The student designs an experiment to study the formation of craters. The materials for the experiment are marbles and a pan of flour. The student makes a hypothesis that the size of the craters made on the surface of the flour will depend on the height from which the marble is dropped. Some of the steps in the student's experiment are described in the picture. Which of these is most likely Step 3 in the student's experiment? (5.6D)
Drop the same marble from different heights into the pan of flour
Drop marbles of different masses from the same height into the pan of flour
Drop marbles of different sizes from different heights into the pan of flour
Drop a single marble one time into the pan of flour
The blades of the fan are moving to move the car forward.
WHICH OF THE FOLLOWING USES THE SAME TYPE OF ENERGY THAT WAS USED TO MOVE THE CAR FORWARD?
A battery lights a bulb
A horn makes a loud noise
A child rides a bike to school
A star shines bright at night
All of the following are examples demonstrating mechanical energy except -
a fire roasting marshmallows
a fan blowing out air
a girl kicking a ball across the yard
a boy writing with a pen
The diagram below shows a series circuit with three lit bulbs.
HOW MANY OF THE BULBS WILL REMAIN LIT IF THE WIRE IS CUT AT THE POINT SHOWN BY THE ARROW?
0
1
2
3
Why is Bulb 2 not lighting up?
The switch is open and prevents the circuit from working.
Bulb 2 is not connected correctly to the circuit.
Bulb 2 is burnt out, so it isn’t working.
The battery is dead and does not provide any electrical energy.
The flow of electricity in circuits requires a complete path. Look closely at the electric circuit below. What is wrong with the diagram?
The light bulb cannot light because the circuit is not complete.
There is no power source for the circuit.
The wires are cut and therefore are not connected correctly.
Paper clips cannot be used to conduct electricity.
Which part of an automobile could refract light?
windshield
door handle
hubcap
license plate
Which of the following best describes how the objective lens of this microscope helps a scientist observe the organisms that live in pond water?
The objective lens refracts light.
The objective lens reflects light.
The objective lens blocks light.
The objective lens produces light.
1. A student used a bent straw to look at a candle. When he looked through the straw, he could not see the candle.
WHY?
Light travels in all directions.
Light can travel around corners.
Light travels in a straight line.
Light cannot travel through a straw.
