Example Questions
Example Question #1 : Change Strength Of A Push Or Pull
What would happen if a ball was pushed lightly into a wall compared to if it was pushed hard into a wall?
Light push - Move slower, bounce less
Hard push - Move faster, bounce more
They would move the same with the light or hard push.
Hard push - Move slower, bounce less
Light push - Move faster, bounce more
Light push - Move slower, bounce less
Hard push - Move faster, bounce more
If the ball was pushed lightly into the wall it would travel slowly to the wall and bounce back slightly. If the ball is pushed hard into a wall it would travel to the wall quickly and bounce off the wall further and faster. Changing the strength of a push or a pull changes the amount of motion seen.
Example Question #2 : Change Strength Of A Push Or Pull
What would happen if I pulled the tricycle towards me on the grass and then on the cement?
Cement - Slow, harder pull needed
Grass - Faster, softer pull needed
The tricycle would move the same on the grass and the cement.
Grass - Slow, harder pull needed
Cement - Faster, softer pull needed
Grass - Slow, harder pull needed
Cement - Faster, softer pull needed
The tricycle would move faster and easier on the cement than on the grass. It would take more force to get the tricycle to move on the grass because of other forces such as friction.
Example Question #3 : Change Strength Of A Push Or Pull
You want to move an empty soda can across a finish line only using a straw. You are not allowed to touch it. How can you get it across?
The wind will push the air through the straw.
Use the power of your mind.
Blow on the can through the straw.
Blow on the can through the straw.
If you use the straw to push air on the can by blowing through it you will move the can across the finish line. Changing the strength of your blow will move the can at different speeds.
Example Question #4 : Change Strength Of A Push Or Pull
Billy cannot get the bowling ball to reach the pins. How can he change his "push" to hit the pins?
Roll the ball harder
Roll the ball the same
Roll the ball softer
Roll the ball harder
Billy needs to add more strength to his "push" to get the bowling ball to reach the pins and move further down the lane. If he increases the strength that he throws the ball with he will reach the pins.
Example Question #23 : Physical Science
I tried to push and pull my 100-pound dog through the door but he wouldn't move. I was able to move my 10-pound dog through with no problem. Why?
Not enough strength with my push or pull
The dog's legs were stuck
Too much strength with my push or pull
Not enough strength with my push or pull
The 100-pound dog has more mass which makes him harder to move. It would require me to use more force or increase the strength of my push or pull in order to move him. There has to be a change in my strength if the big dog is to move.
Example Question #4 : Change Strength Of A Push Or Pull
To make something move farther you have to push or pull it harder.
True
False
True
This is a true statement. If we want something to move farther or faster we have to push it or pull it harder. Increasing the strength of a push or pull will change the motion.
Example Question #3 : Change Strength Of A Push Or Pull
What will happen to the woman if the other team lets go of the rope?
She will fall down.
She will stay in the same spot.
We can't tell what would happen.
She will fall down.
If the other team lets go of the rope there will be a change in the strength of the pull. This would cause everyone who is pulling on the opposite side to fall down. This woman would likely fall into the muddy water because there is no one pulling against her on the other side.
Example Question #6 : Change Strength Of A Push Or Pull
Jerry is pulling this wagon and wants it to go faster, how could he do this?
Pull it the same
Pull softer
Pull harder
Pull harder
If Jerry wants the wagon to move faster he will have to change the strength that he pulls with. The harder he pulls it the faster it will move.
Example Question #4 : Change Strength Of A Push Or Pull
A boy rolls a regular marble down a ruler and hits a cup. He does it again with a very tiny marble this time. What will happen?
The tiny marble will move the cup the same as the regular marble.
The tiny marble will not move the cup as far.
The tiny marble will move the cup further.
The tiny marble will not move the cup as far.
The tiny marble has less force behind it so it will cause the cup to move a shorter distance than when it was hit with the regular marble. The strength of a push or pull can be changed. The more mass something has the more force it has, the less mass something has (like a tiny marble) the less force it has.
Example Question #8 : Change Strength Of A Push Or Pull
At the fair my friends played Tug-of-War. There were 5 people on each team. After pulling for a few minutes no one won. Why did neither team win?
They were pulling with the same strength.
One team gave up before it was over.
Tug-of-War always ends in a tie.
They were pulling with the same strength.
Neither team won because they were both pulling with the same strength. If neither team pulls harder than the other the game will end in a tie and neither team will win.
