Motion
100
Where are objects pulled towards with this force?
What is Earth
100
What is the first part of Newton's Law of motion?
What is an object at rest will remain at rest until an unbalanced force acts on it.
100
How does friction help?
It can slow down an object or stop it
100
When a car moves around a corner, what is happening?
What is changing direction
100
what is motion?
What is any changing position of an object
200
What is gravity?
Where one object is pulling on another object. Because of gravity, objects are pulled towards the Earth
200
what is the second part of Newton's Law of Motion?
What is an object in motion will stay in motion in a straight line until an unbalanced force acts on it.
200
what happened to Herman in the story that dealt with friction?
There was too much friction when his belly was rubbing against the floor causing him to move very slowly.
200
Mrs. J's and Mrs. Bain discovered that the marble traveled a greater distance when Mrs. J pushed it across the floor. Why?
What is Mrs. J applied a greater push (force) than Mrs. B
200
Describe 3 ways a push or a pull can change the way an object moves.
What is it can change the direction of an object, it can slow it down, it can speed it up, it can stop an object or start an object.
300
How is the flight of a paper airplane in a spacecraft?
The plane does not fall down to the ground because of "zero gravity"
300
Mrs. J got into a car accident, there was a soccer ball in the back seat, what happened to the ball when the car crashed and stopped?
What is the ball kept in motion
300
what is friction?
What is a force caused by surfaces rubbing against each other
300
How do you change the motion of a ball to increase its speed?
What is push or pull the ball with added force to increase its speed.
300
Mrs. J and Mrs. B were observing and measuring the motion of toy jumping frogs. How did they know that the grog had moved?
The jumping frogs changed position
400
sally and Kristy were testing the flight of an airplane as they tossed them across the classroom. the planes flew across and landed on the floor. Why?
What is gravity was pulling down on them bringing them to the floor.
400
Describe what happens to the toy mouse in outer space.
What is it keeps moving
400
when performing an investigation with friction, it is best to do it how many times?
What is 3 times
400
If two marbles are being investigated and they had different weights, a heavy one and a light one. Which one would need more force to move?
What is the heavier one because the more mass an object has the more force is needed to move it.
400
What force was needed to get the toy frogs moving?
What is a push
500
If a table is on a desk and it is not moving, what are the forces involved?
What is gravity is pushing down on it and the table is pushing up on the book.
500
what is newtons law of motion?
What is an object at rest will remain at rest and an object in motion will stay in motion until an ubalanced force acts on it.
500
how does walking on grass differ from walking on ice?
What is grass has more friction and ice has less friction so it is slippery
500
motion can be described by?
What is speed, direction and distance
500

What are fast, slow, up, down, straight, curve, right, left
