Newton's Laws
This law says that an object at rest stays at rest unless acted on by a force.
What is Newton’s First Law?
The ability to do work is called this.
What is energy?
Everything around us is made of this.
What is matter?
This tells how fast an object moves over a distance.
What is speed?
The first step of the scientific method is usually making one of these about the world around you.
What is an observation?
This force pulls objects toward Earth and keeps planets in orbit.
What is gravity?
Stored energy, like energy in a stretched rubber band or food, is called this type of energy.
What is potential energy?
A substance made of only one type of atom is called this.
What is an element?
If a car changes its speed or direction, it is experiencing this.
What is acceleration?
A testable explanation for a scientific question is called this.
What is a hypothesis?
If you push a shopping cart harder, it speeds up more. This demonstrates this law.
What is Newton’s Second Law?
Energy of motion is called this.
What is kinetic energy?
When two or more elements chemically combine, they form this.
What is a compound?
This formula is used to calculate speed.
What is speed = distance ÷ time?
In an experiment, the variable that is purposely changed is called this.
What is the independent variable?
When a swimmer pushes water backward, the water pushes the swimmer forward. This is an example of this law.
What is Newton’s Third Law?
This law states that energy cannot be created or destroyed, only changed from one form to another.
What is the Law of Conservation of Energy?
This part of the atom has a positive charge and is found in the nucleus.
What is a proton?
A roller coaster speeding up down a hill is an example of this type of acceleration.
What is positive acceleration?
Scientists around the world use this measurement system.
What is the metric system?
A rocket launches because hot gases are pushed downward while the rocket is pushed upward. This pair of forces is called this.
What is action and reaction?
When a roller coaster reaches the top of a hill, it has mostly this type of energy, but as it speeds downhill, it changes into another type. Name both forms.
What are potential energy and kinetic energy?
In a chemical reaction, matter is not created or destroyed. This scientific rule is called this.
What is the Law of Conservation of Mass?
A car slowing from 60 mph to 20 mph at a red light is experiencing this type of acceleration.
What is deceleration (negative acceleration)?
The unit used to measure mass in science labs is commonly this.
What is the gram?
