What is Force?
A force is an action that changes or maintains the motion of a body or object. Simply stated, a force is a push or a pull. Forces can change an object’s speed, its direction, and even its shape. Pushing a door open, pulling it closed, stretching a rubber band—all of these actions require force.
What is Gravity?
On Earth gravity pulls objects toward the center of Earth. This is what makes objects fall. It is also what gives an object weight. Weight is a measurement of the force of gravity between an object and the surface it stands on. If a person stands on a scale, gravity pulls the person against the scale. The scale shows the strength of this force, or the person’s weight.

Is baking cookies more of a physical or chemical change?
Chemical (baking soda).
No, it is a Compound Machine
Describe to me all 3 of Newton's Laws of Motion. I will give points for 2/3 correct.
The first law states that the motion of an object will not change unless an unbalanced force pushes or pulls on the object. In his second law, Newton related force with mass and acceleration, showing that a strong force makes an object move faster than a weak force acting on the same object. Newton’s third law shows that whenever a force pushes an object, the object pushes back with an equal and opposite force.
How many times has Miss Elena seen Beyoncé in concert?

About how long does it take from light far away in space to reach Earth?
about 1 billion years
What is the equation for density?
D=M/V
Density = Mass divided by Volume
What is the goal of a Rube Goldberg Machine?
A Rube Goldberg machine is a complex contraption designed to complete a simple task. The machine uses a set of tasks that work in succession and trigger one event after another until the final event. It’s actually listed in the Merriam-Webster dictionary as an adjective that means “doing something simple in a very complicated way that is not necessary.”
A car rolling down a hill and then hitting a tree is an example of which of Newton's Laws of Motion?
Newton's first law
