Example Questions
Example Question #1 : Change Speed/Direction Of Objects With Pushes/Pulls
If a rolling ball hits another ball, what do you think will happen?
They will both stop right away.
They will continue on with no changes.
They will change speed or direction.
They will change speed or direction.
If a rolling ball hits another ball they will change directions or speeds based on the force applied. When we push the balls into each other their force is redirected.
Example Question #1 : Change Speed/Direction Of Objects With Pushes/Pulls
If you roll a ball harder, what do you think will happen?
It will roll slower and farther.
It will roll faster and farther.
It will roll slower and less distance.
It will roll faster and farther.
If a ball if pushed harder it will roll faster and further in a straight line unless interrupted by another force. Adding more force will change the ball's speed.
Example Question #3 : Change Speed/Direction Of Objects With Pushes/Pulls
A moving object can change direction and the direction of other objects.
False
True
True
This is true. All objects have force so when they collide they are able to change the direction or speed of what they hit. Their own speed or direction may also change because of the collision.
Example Question #1 : Change Speed/Direction Of Objects With Pushes/Pulls
What does it mean to push something?
How fast something is moving
Use force to move towards
Use force to move away
Use force to move away
A push is a force that moves something away from where it starts. If I push a friend on a swing they will move away from me. How fast or far they go depends on how hard I push.
Example Question #12 : Solutions To Change Speed Or Direction
What is a pull?
Use force to move away
Use force to move towards
The path of the object
Use force to move towards
A pull means to use force to move towards something. If I pull on a toy that my dog has in his mouth I will move the dog and toy towards me while I am pulling.
Example Question #151 : Kindergarten Science
Lily pulls on a rope toy that her dog is chewing on. The dog stays in the same exact spot and doesn't move. Did she change the dog's direction?
There is not enough evidence to tell if she made a change.
Yes, she did change the dog's direction.
No, she did not change the dog's direction.
No, she did not change the dog's direction.
No, she did not change the dog's direction. She applied force but not enough to make a change. If she wanted to create a solution to move the dog she would have to pull harder.
Example Question #41 : Physical Science
Mike pushed his sister on the swing. She wanted to go faster! What should Mike do to change her speed?
Mike should stop pushing
Mike should push harder
Mike should push softer
Mike should push harder
If Mike's sister wants to go faster he should push harder. By applying more force he can change the speed that his sister swings. Pushing harder will make her swing faster (and higher).
Example Question #14 : Solutions To Change Speed Or Direction
Jake flew his drone. When he threw a rock at the drone it moved to the side. How could he test to see if this is always true?
Throw different objects at the drone instead
Just guess it will happen and keep playing
Repeat the throw more times
Repeat the throw more times
Jake could repeat the action more times to see if this always happens. When two moving objects collide they will change speed and direction because of the push from one object to the other.
Example Question #15 : Solutions To Change Speed Or Direction
If Mary wants her toy car to move down a ramp faster, how should she do it?
Make the ramp taller
Do not change the ramp at all
Make the ramp shorter
Make the ramp taller
Mary should make her ramp taller so the car can gain more speed. The pull of gravity on a taller ramp will increase the car's speed.
Example Question #1 : Change Speed/Direction Of Objects With Pushes/Pulls
Which results prove a push or pull changed the object’s speed?
The ball was rolling straight and then sped up when hit.
The ball was rolling straight and kept moving.
The ball was rolling straight and then moved left.
The ball was rolling straight and then sped up when hit.
If the ball sped up after it was hit, that means the push of another object colliding with it caused a change in speed. In this case, there was an increase in speed when the hit took place.
