Going through changes
A push or a pull that causes an object's motion to change.
What is force
This is the ability to do work or cause change.
What is energy?
The famous scientist who came up with three important laws about how objects move because of forces.
Who is Isaac Newton?
What unit is used to measure force?
(200 points) If you push a heavy skateboard and a light toy car with the exact same amount of force, the toy car will do this much faster.
What is accelerate?
The force that attracts objects to the Earth
The law that states energy can't be created or destroyed, only transformed.
What is the law of thermodynamics?
An object at rest will stay at rest, and an object in motion will stay in motion unless a force acts on it.
What is Newton's First Law of Motion?
What tool is used to measure force?
What is a spring scale?
(400 points) When you jump off a small dock into a canoe, the canoe shoots backward into the water, this is an example of this Newton's Law
What is Newton's Third Law?
When one force is stronger than the other resulting in motion.
What is unbalanced force
What is open circuit?
F = m (x) a
What is Newton's Second Law of Motion?
This is another name for Newton's first law of motion.
What is inertia?
(600 points)
A satellite is coasting through deep space at a constant speed of 10,000 miles per hour. This is the total net force acting on the satellite.
What is zero? (constant speed can also mean balanced forces, especially if there is no friction)
When two equal forces act in opposite directions, resulting in no motion
A completely unbroken track that allows electricity to circulate continuously.
What is a circuit?
When a force acts on a mass, it causes acceleration.
What is Newton's Second Law of Motion?
On Earth, what does gravity pull objects towards?
What is the center?
(800 points) We used copper wire for the spinning frame of the homopolar motor because copper is an excellent source one of these, allowing electricity to flow freely.
What is conductor?
A skateboarder rolls down the sidewalk at a steady speed and glides through a smooth, gentle curve. During the turn, the forces acting on the skateboarder are this.
What is unbalanced?
When you turn on a flashlight with batteries in it, this energy from the battery is transformed into electrical energy, and then to light.
What is chemical energy?
The more mass an object has, the stronger this pull is.
What is gravity?
This is a force that opposes motion when two surfaces touch?
What is friction?
(1000) These two are permanently linked because of the way moving electrical charges spontaneously project their own fields.
What are electricity and magnetism?
