Types of Energy
This type of energy is stored in a stretched rubber band.
What is elastic potential energy?
This law states that an object in motion will stay in motion unless acted upon by a force.
What is Newton's First Law?
This term refers to the ratio of useful energy output to total energy input.
What is energy efficiency?
When forces on an object are equal and opposite, they are described as this.
What are balanced forces?
In a time-speed graph, this indicates that the object is stationary.
What is a horizontal line at zero speed?
The energy that comes from heat is called this.
What is thermal energy?
The principle of action and reaction relates to this law.
What is Newton's Third Law?
An energy-efficient light bulb produces more of this type of energy and less heat.
What is light energy?
An object will accelerate if the forces acting on it are this.
What are unbalanced forces?
A straight upward-sloping line on a time-speed graph shows this.
What is constant acceleration?
Energy due to motion is referred to as this.
What is kinetic energy?
The equation F = ma is derived from this law.
What is Newton's Second Law?
The wasted energy in most energy transformations is typically released as this.
What is heat (thermal energy)?
If a 100 N force is applied to the right and a 50 N force is applied to the left, the object will move in this direction.
What is to the right?
This type of graph plots an object’s speed as it changes over time.
What is a time-speed graph?
Energy stored in the bonds of chemical compounds is called this.
What is chemical energy?
A soccer ball at rest remains stationary until kicked, an example of this law.
What is Newton's First Law?
Appliances with this label in many countries are designed to use less energy while performing the same task.
What is ENERGY STAR?
Two children pushing on opposite sides of a stationary swing with equal force illustrates this type of force.
What are balanced forces?
A straight, horizontal line on a time-speed graph means this about the object's speed.
What is constant speed?
The energy related to an object’s position or height is known as this.
What is gravitational potential energy?
This law explains why rockets are propelled forward by expelling gas backward.
What is Newton's Third Law?
This type of diagram visually represents energy transformations and efficiency losses.
What is a Sankey diagram?
This is the net force when forces on an object are balanced.
What is zero?
A steep downward-sloping line on a time-speed graph represents this.
What is deceleration?
