The speed and direction of an object are considered this.
What is velocity?
Grams, milligrams, kilograms, and pounds are all ways we measure this.
What is weight?
The ability to do work is this.
What is energy?
Force is this.
What is a push or a pull?
An example of a lever is this. Bonus points if you name what class...

The distance something travels divided by how much time it takes is this. For example, something that travels 1 mile in 60 seconds would travel 60 miles per hour (mph).
What is speed?
The force that pulls on all objects, and increases the bigger something is but gets weaker if it is far away is this.
What is gravity?
When you transfer energy from one object to another, you are doing this.
What is work?
This law states that force is mass times acceleration (F = ma).
What is Newton's Second Law?
True or false: A screw is an inclined plane wrapped around a cylinder.
What is true?
Any change in position is this.
What is motion?
The amount of matter in something is this.
What is mass?
Measuring work or energy is done using this.
This is an example of Newton's First Law of Motion.
"What is when a car comes to a sudden stop and the person keeps moving forward until the seatbelt stops them."
"What is the law of inertia, meaning a ball will continue to roll on the ground unless an outside force, like friction or gravity stop it."
Look around the room. Name two simple machines you see.

The rate that the velocity of an object changes is this.
What is acceleration?
True or False: Mass and weight are the same thing.
What is false.
The Law of the Conservation of Energy states this.
What is energy can never be created or destroyed?
This is the force that opposes motion between two surfaces, often creating heat.
A simple machine takes a force and changes this.
What are its direction, distance, or strength?
If a beetle flies to a flower 12 meters away in 4 seconds, its speed is this. How long would it take the beetle to fly to a tree 20 meters away?
What is 3 meters per second (m/s) and 60 seconds?
This is why your weight on the moon would be less than your weight on Earth, but your mass would be the same.
What is your weight is determined by the amount of gravity pulling on you, and the moon has less gravity because it is smaller, so you weigh less. Your mass never changes.
Another word for stored energy is this, while energy of an object in motion is this.
What are potential and kinetic energy?
This is an example of Newton's Third Law.
Possible answers:
"For every action there is an equal and opposite reaction, like walking- your foot pushes on the ground, and the ground pushes back propelling you forward."
"Two people on ice pushing against each other are pushed away from one another."
