A
Name a metal that can be attracted to a magnet
Iron (some steel), nickel, cobalt
What do we call the push or pull on an object?
Force
What is motion?
The change in position of an object
What is friction?
a force when you rub two things together and it causes it to slow down or stop
What happens when the same sides of a magnet's poles face each other? (a north facing a north or a south facing a south)
They repel each other
What is the force that pulls objects toward each other?
Gravity
What is it called when a force causes an object to speed up?
Name a type of contact force
Friction, pushing or pulling an object
What is the strongest part of the magnet?
The poles
What is acceleration?
when something speeds up, slows down, or changes direction
Give an example of a non-contact force
Magnetism, electric force, gravity
What is an example of a push?
Pushing a door open
What is it called when forces are equal and do not cause motion?
Balanced Forces
What happens when you push a toy car harder?
It speeds up
If two things the same weight and size are using the same amount of force, the force will be
balanced
Describe what happens when two magnets are brought together with opposite poles.
They attract each other
What do we call the push or pull on an object?
Force
What happens when there are unbalanced forces?
The object will accelerate or change direction
If two dogs of different size play tug of war, and they cannot pull with the same amount of force, what kind of force is it?
Unbalanced
what do we call a force that moves objects away?
a push
What does static electricity do?
It can cause objects to stick together or repel each other.
What is the difference between weight and mass?
Weight is the force of gravity on an object; mass is the amount of matter in the object.
Give an example of a balanced force
two dogs of the same size and weight playing tug-of-war
What would happen if we didn't have friction?
We would not be able to walk; we would slip and fall
what do we call a force that moves objects closer?
a pull
