Energy
Rubbing two sticks together more quickly to start a fire, what would increase your chances of getting the fire started by increasing this type of energy transfer.
What is kinetic to thermal?
Red, Orange, Yellow, Green, Indigo and Violet are all parts of this.
What is the visible spectrum?
This is the formula for density.
What is density= mass/volume?
Meters/second would be a measure of this.
What is speed?
This type of field is only attractive.
What is a gravitational field?
The Law of Conservation of Energy states this.
What is that energy is neither created or destroyed, just transferred from one form to another?
This color of sweatshirt would keep you the coolest on a sunny day.
What is a black sweatshirt?
There are this number of elements in one molecule of H2O.
What is two?
Height and mass would increase this type of potential energy.
What is gravitational potential energy?
This type of field can be both attractive and repulsive.
What is a magnetic field?
Energy from the sun is transformed into this type of energy during photosynthesis.
What is chemical energy?
A wave's displacement from its state of rest is known as this.
What is amplitude?
Flexibility, color, and density would be examples of this type of property.
What is a physical property?
This type of force would cause an object to change speed or direction.
What is an unbalanced force?
These two variables affect the strength of gravity.
What is distance and mass?
This property of a black sweatshirt allows it to become more hot in the sun.
What is absorption?
A sound will travel faster in this type of medium.
What is a denser medium?
Products being hotter than the reactants would indicate this type of chemical reaction.
What is exothermic?
An object in motion will stay in motion unless acted upon by an unbalanced force is the premise of this law of physics.
What is Newton's 1st Law of Motion?
Magnetic domains staying aligned for a short amount of time would be a characteristic of this.
What is a temporary magnet?
Using a fireplace to warm a home's inhabitants would be and example of this type of energy transfer.
What is chemical to thermal?
Increasing this would have the greatest effect on a sound wave's energy.
What is amplitude?
These would be two ways of determining whether a solid is less dense than water.
What is putting it in water to see if it floats or calculating its density to see if it is less than 1g/cm3?
Whenever one object exerts a force on another object, the second object exerts an equal and opposite on the first, is stated under this law in physics
What is Newton's 3rd Law of Motion?
When magnets and gravity act on objects that are separated from them it is known as this type of force.
What is force-at-a-distance?
