What is a force?
If you push a swing harder, this happens to its motion.
What is it goes higher or faster?

What is gravity pulling down?
When forces on an object are balanced, its motion does this.
What is stay the same?
In science, we test ideas by doing one of these.
What is an experiment?
When forces are equal and opposite, we say they are this.
What are balanced forces?
What force is used to pull a magnet across a table without touching it?
Magnetic force.
When you jump off a step, what force pulls you back to the ground?
What is gravity?
When a ball is thrown upward, gravity causes it to do this.
What is slow down and fall back down?
In the “Balancing Forces” unit, scientists studied why this object stayed in the air.
What is the floating train or hover train?
When forces are not equal and cause a change in motion.
What are unbalanced forces?
A ball rolling on the floor eventually stops because of this force.
What is friction?
When you slide a book across a table, which force tries to stop it
What is friction?
If an object is not moving, what can we say about the forces on it?
What are balanced forces
Students used this type of model to show how forces can be balanced.
What is a diagram?
The force that pulls objects toward the center of the Earth.
What is gravity?
If two students push a box in opposite directions with equal strength, what happens to the box?
it doesn’t move
Why might two magnets seem to “float” above each other?
Their like poles are repelling each other.
When a magnet attracts a nail, what happens to the nail’s motion?
What is it moves toward the magnet?
We can show the direction of a force using one of these.
