100
a force because it pulls or pushes objects if they are made of a magnetic material
Magnetism
100
force used to move an object using our muscles
Muscular Force
100
An object at rest stays at rest and an object in motion will remain in motion unless acted on by an external force
Newton's First Law
100
A force that makes it harder to slide objects across each other
Friction
100
Kicking a soccer ball is a what kind of force
Push force
100
Examples of this force are gravity, electrostatic, and magnetism
Non-Contact Force
100
You jump from the top of the play structure on the recess yard
Unbalanced
200
is an invisible force that happens when magnets either attract or repel each othe
Magnetism
200
force made by a compressed or stretched spring upon any object that is attached to it.
Spring Force
200
The acceleration of an object is directly proportional to the net force acting on the object, and inversely proportional to the mass of the object.
Newton's Second Law
200
The frictional force that keeps an objects still
Static Friction
200
Opening a door is what kind of force
Pull force
200
electrical charges move from one object to another, they can cause static electricity
Static electricity
200
happens when 2 equal forces act on an object in opposite directions.
Balanced force
300
Have a north and south pole
Magnets
300
When bicycle brake pads squeeze a bike tire to stop it, it is which force in action
Frictional Force
300
A person pushing a shopping cart will need to exert more force to accelerate a heavily loaded cart than a lightly loaded cart
Newton's second Law
300
The frictional force that slows the movement of two surfaces that slide against one another
Sliding Friction
300
Definition of a Push force
A push force happens when a force moves an object away.
300
Everything is made up of tiny particles that are too small to be seen. These tiny particles can have an electrical charge, either positive or negative. When two particles are the same, they repel (push away) each other. If they are opposite, they attract (pull towards) each other
Electrostatic Force
300
a force that changes the position, speed, or direction of an object to which the force is applied.
Unbalanced force
400
Repel
400
A force that touches an object to move it
Contact Force
400
A person sitting in a chair will remain sitting in the chair until acted upon by a force (such as someone pushing them out of the chair).
Newton's first law
400
The frictional force that slows the movement when an on object rolls over it
Rolling Friction
400
Definition of a pull force
happens when a force brings an object closer.
400
force acts on an object without touching it.
Non- Contact force
400
You’re trying to figure out if you or your teacher is stronger. So you do an arm wrestle but both of your hands don’t move.
Balanced forces
500
Attract
500
Springs will have more force when they are compressed further. As you compress the spring further, it gets more ____.
Potential Energy
500
for every action, there is an equal and opposite reaction
Newton's Third Law
500
A person going down a slide at a playground

500
Going down a slide is a ____ Force
Pulling force
500
A ball comes back down to the Earth because of
Gravity
500
When 2 equal forces are applied on an object in opposite directions, the net force is
Balanced Force
