Types of Energy
This type of energy is the energy of motion.
Kinetic Energy (KE)
This law states that an object at rest stays at rest unless acted on by an outside force.
Newton's First Law of Motion (Law of Inertia)
What is pressure?
The amount of force applied to an object
When the forces on an object are equal and cancel each other out they are called these.
Balanced forces
What is the full name of the scientist who developed the three laws of motion?
Sir Isaac Newton
This type of energy is stored energy based on position or shape.
Potential Energy (PE)
This law says that every action has an equal and opposite reaction (think Newton's cradle)
Newton's Third Law of Motion
Force is a _______ or ________ on an object.
Push or Pull
These forces cause a change in motion, like speeding up, slowing down, or changing direction.
Unbalanced forces.
How does mass affect acceleration?
The more mass, the more force is required for movement.
This form of energy is stored in the bonds between atoms and released during reactions.
Chemical Energy (CE)
This law explains how acceleration depends on force and mass, often written as F=ma
Newton's Second Law of Motion
What is a contact force?
Force between two objects that are physically touching each other
A book sitting on a table is an example of these types of forces acting on it.
Balanced forces
Earlier this month, Ms. Larned fell and injured her elbow. What forces are at play?
Gravity and Friction
This type of energy is caused by the movement of electric charges through a conductor, like in a wire powering a device.
Electrical Energy
This law explains why pushing an empty shopping cart is easier than pushing a full one.
Newton's Second Law of Motion
Is friction a contact or non-contact force?
Contact force
A soccer ball at rest is kicked and begins moving forward; this change is caused by these types of forces.
Unbalanced forces.
This force slows down objects when two surfaces rub against each other.
Friction
This type of energy is associated with the random movement of particles and if often measured as temperature.
Thermal Energy (TE)
A soccer ball rolls on the grass until friction or another force stops it - what law describes this behavior?
Newton's First Law of Motion
What is acceleration?
The rate at which an object speeds up or changes direction.
If forces on an object are unbalanced, the object will experience this. (Vocab word)
Acceleration
What inspired Isaac to start investigating gravitiy/motion?
He watched an apple fall from a tree.
