Total questions: 18
Worksheet time: 14mins
What is a pattern of motion?
A motion that is random
A motion that repeats
Any typr of regular force
What is friction?
Friction is another word for a pushing and pulling force. It speeds things up.
Friction is the force that pulls objects down to the surface of the Earth.
Friction is the force that resists motion. It slows things down.
Explain the relationship between string length and motion for pendulums.
The longer the string length, the faster a pendulum swings. The shorter the string length, the slower a pendulum swings.
The longer the string length, the slower a pendulum swings. The shorter the string length, the faster a pendulum swings.
There is no difference between the string length and motion for pendulums

B. It will slow down.
C. It will start moving.
D. It will not move.
E. It will change direction.
The ball is rolling toward Jason before he blows on it. Select the BEST prediction for what will happen to the ping-pong ball after Jason blows on it.
A. It will speed up.
B. It will start moving.
C. It will not move.
D. It will slow down.

A. It will speed up.
B. It will change direction
C. It will not move.
D. It will slow down.
WHY is Lisa able to PREDICT how her cousins will be moving in the future?
A. Lisa observes that one swing is shorter than the other.
B. Lisa observes that Beth moves farther than Jenny does.
C. Lisa observes that the motion of each swing happens in a pattern.
D. Lisa observes that Beth moves back and forth more times than Jenny does.
During Experiment 1, a student pushes car X much closer to the center of the seesaw. Which statements BEST predict what will happen to the forces and motion as soon as car X starts to move? Select the TWO correct answers.
The seesaw will begin to tilt.
The seesaw will stop moving and be flat.
The forces on the seesaw will become balanced.
The forces on the see saw will become unbalanced.
The seesaw will move up and down in a repeated pattern.
After school, two students with the same mass (weight) sit on on opposite sides of a seesaw on the playground. They want to repeat Experiment 1. How can the students cause the forces on the seesaw to become balanced?
Both students can push up and down on the seesaw.
One of the students can move to the center of the seesaw.
The students can ask a friend to sit on the left side of the seesaw.
The students can each sit at the same distance from the center of a seesaw.
Which statement BEST predicts how the ruler will move after a few minutes have passed? These two cars have the same mass (weight).
The ruler will stop moving, with car X's side of the ruler tilted downward.
The ruler will tilt up and down faster than when first pushed.
The ruler will move more slowly and stay more flat than when first pushed.
The ruler will not be moving, and car W's side of the ruler will be sitting on the triangular block.
Which statement BEST predicts how one of the cars will move at the beginning of experiment 3?
Car X will roll across the ruler toward car W.
Car W will roll to the center of the ruler and stop.
Car W will roll across the ruler and crash into car X.
Car X will roll away from car W.
How can the students move a car to cause the forces to become balanced?
Push car W toward the edge of the ruler, and push car X toward the center of the ruler.
Push car X toward the center of the ruler.
Push car W and car X equal distances toward the center of the ruler.
Push car W toward the center of the ruler.
Which of the following are BOTH materials that would create a lot of friction?
Carpet and water
Tile floor and a blanket
Carpet and sandpaper
Plastic and tile floor
Which of the following are BOTH materials that would NOT create a lot of friction when they rub together?
Rubber and wood
A glass bowl and soapy water
A sidewalk and new running shoes
Carpet and sandpaper
The ball is not moving before Jason blows on it. Select the BEST prediction for what will happen to the ping-pong ball after Jason blows on it.
It will speed up.
It will start moving.
It will change direction.
It will not move.
What is a lever?
A simple tool or machine that uses force to move a load around a pivot, or fulcrum. This makes work easier.
A weight hung from a point so it can swing freely back and forth under the action of gravity.
a force that causes moving things to slow down when one object rubs against another object
a pattern of motion is motion that repeats and is predictable
What is a pendulum?
a pattern of motion is motion that repeats and is predictable
a force that causes moving things to slow down when one object rubs against another object
A simple tool or machine that uses force to move a load around a pivot, or fulcrum.
A weight hung from a point so it can swing freely back and forth under the action of gravity.
Which of these are examples of levers? Choose all correct answers.
seesaw
swing
scissors
broom
