Newton's First Law
Newton's First Law: An object in motion tends to stay in ___________.
What is motion?
This measurement is important for determining how much force is required to move an object or change direction.
What is mass?
When one ball collides with another stationary ball, the first ball stops, but the second ball ___________.
What is moves?
This type of electricity is caused by a buildup of electric charges on an object, often after electrons are transferred from one object to another.
What is static electricity?
A magnet is surrounded by a magnetic __________ that allows its force to act on objects at a distance.
What is field?
Newton's First Law: An object at rest tends to stay at _____________.
What is rest?
This is a measurement of a moving object's mass times its velocity.
What is momentum?
Newton's Third Law states that for every action there is a __________.
What is reaction?
When two objects have these types of electric charges, they push away from each other.
What are like charges?
What are poles?
This science term describes a push or pull.
What is force?
When an object is at rest, the forces acting upon it are ______________.
What is balanced?
For every action, the reaction is in the ________________ direction.
What is opposite?
A balloon rubbed on someone's hair becomes negatively charged because these particles move from the hair to the balloon.
What are electrons?
Like magnetic fields do this to each other.
What is repel?
This common force causes many moving things to stop moving. For example, you push a cart across the floor and it slowly stops because of this force.
What is friction?
When an object changes motion, it is because the forces acting on it are __________________.
What is unbalanced?
For every action, there is an _______________ and opposite reation.
What is equal?
A charged balloon can make a student's hair stand up even without touching it. This demonstrates that electric forces can act through this invisible region around a charged object.
What is an electric field?
Opposite magnetic forces do this to each other.
What is attract?
Newton's First Law describes this scientific concept.
What is inertia?
When an object is in constant motion without changes, the forces acting upon it are ____________________.
What is unbalanced?
Even though we say the action has a reaction, these actions happen at the same __________.
What is time?
A student charges a balloon and holds it near small pieces of paper. The paper pieces are attracted to the balloon even though the balloon never touches them. These forces are acting at a ___________.
What is distance?
This is what is created when you run a current through a wire.
What is magnetic field?
