Energy!
This is one of the ways energy is transferred to an object by applying a force over a distance in the direction of the force.
What is work?
This is another way to describe a theory
This is the tendency of an object to resist change in its state in motion.
What is inertia?
This scientist used an observatory to observe a nova, proving stars were not perfect or unchanging
Consider a large, ideal (frictionless) pendulum with a steel ball weighing 27.05 lb on the end. What is the mass if the ball?
12.30 kg
A perfect pendulum is one that loses no energy due to this
What is friction?
These are used to support a theory and are subject to change depending on experimentation and observation
What are scientific facts?
This is the force with which gravity is pulling on an object
What is weight?
This scientist hypothesized a star’s apparent location change during a solar eclipse proving light is affected by gravity. (Relativity)
Who is Albert Einstein?
222.7 J
At this point in a pendulum's swing, there is only gravitational potential energy and no kinetic energy
What is it's highest point?
This is the process of using experimentation, observation, and logical thinking to build our understanding of the world
What is science?
This is proportional to the force acting on it
What is acceleration?
This scientist discovered each of the planetary orbits is an ellipse, with the sun at one focus.
Who is Johannes Kepler?
Protons have a mass of 1.675 × 10–24 g. Determine the kinetic energy of a neutron traveling at 22.7% of the speed of light.
5.70x10-20 J
What is chemical potential energy?
This is evident and obvious to us through general revelation or through special revelation, it does not change
What is truth?
This law is applied when a rocket pushes down on its fuel which thrusts the rocket upward.
What is Newton's Third Law?
For fear of offending the church, this scientist published his theory that the sun is at the center of the universe only to his friends
Who is Nicolaus Copernicus?
A girl drops a stone into the water from a bridge. The stone has a mass of 325 g and the bridge is 36.1 m above the water. How fast will the stone be moving just before it hits the water?
26.6 m/s
This energy describes stretching or compressing something
What is elastic energy?
This is a positively stated, informed prediction about what will happen in certain circumstances
What is a hypothesis?
A kid on a sled slides down a snow-covered hill but hits rough spot of grass at the bottom. This law explains why his sled suddenly stops.
What is Newton's First law?
This scientist theorized every object in the universe pulls on every other object in the universe
Who is Isaac Newton?
A polarized molecule with a mass of 2.75 × 10–11 ng is accelerated in an electric field with a force of 576.7 μN. Determine the acceleration of the molecule.
2.10 m/s2
