100

What is a force?

Eddy and Mary are in a Tug-of-War game with Yolanda and Blake. If Eddy and Mary are pulling with a greater force, which direction will the rope move?
It will move towards Eddy and Mary.
100
An object that can pull certain types of metal towards it.
What is a magnet?
200
Forces acting on an object that do not cause the object to move.
What are balanced forces?

Ms. Peyton's car stopped running and she had to push it off the road. What is most likely to change about the car when she pushes it?
A. The mass of the car
B. The position of the car
B. The position of the car will change because if you have enough force, it will cause an object to move.
200
The area around a magnet that has magnetic force.
What is a magnetic field?
300
Forces acting on an object that cause an object to move.
What are unbalanced forces?
300
What will happen when the two teams both pull with the force of 500 Newtons?
Nobody will win, and the teams will not move because the forces are equal. This is an example of a balanced force!
300
The force that can attract or repel objects with magnetic material.
Magnetism (Magnetic Force)
400
A force that pulls objects toward each other.
What is gravity?
400
What will happen when one team pulls with the force of 450 Newtons, and one team pulls with the force of 500 Newtons?
The team that pulls with the force of 500 Newtons will win, and the rope will move towards the team with the stronger force! This is an example of a unbalanced force.

This picture shows two magnets pointed towards each other with iron filings around them. Looking at the iron filings, where is the magnetic field the strongest?
A. Above the magnets
B. Below the magnets
C. In the middle between the poles of the magnets
C. In the middle between the poles of the magnets is where the magnetic field is the strongest. You can tell because the most iron filings are collected there on the poles.
500
A force that acts between objects that rub together.
What is friction?

Two children are playing with toy cars that are identical. Each child sets their toy car down on the ground and pushes it. The first child's car goes twice as far as the second child's car. What reason could explain why one car traveled further?
A. Child 1's car is smaller than Child 2's
B. Child 1 pushes the car with a greater force than Child 2.
B. Child 1 pushes the car with a greater force than Child 2, so the car moved further. Since the cars are identical, A would not be the correct choice.

What will happen to two magnets when you point the North pole of each magnet towards each other?
(Use the word attract or repel in your answer)
The two magnets will repel each other, because if poles are the same, they repel each other.
