This mathematician and astronomer brought forward the idea of Heliocentrism in his book "On the Revolutions of the Celestial Spheres," published in 1543.
Nicolaus Copernicus
What is the equation for Force that Newton presents in his Second Law of Motion?
Force = Mass x Acceleration
In 1609, Galileo built an improved version of this instrument, allowing him to make groundbreaking astronomical discoveries.
Telescope
In projectile motion, what is the path followed by the projectile called?
Trajectory
When a skateboarder goes down a ramp, potential energy converts into what type of energy?
Kinetic Energy
This astronomer was tried and convicted of heresy and placed under house arrest by the Roman Inquisition for championing Copernicus' theory of Heliocentrism, in opposition to the geocentric model of the time.
Galileo Galilei
What are the two parts of Newton's First Law of Motion?
1. An object in motion stays in motion;
2. An object at rest stays at rest;
Until acted on by an outside force
Galileo proved that objects fall at the same rate regardless of their mass by throwing cannon balls off what famous Italian landmark?
Leaning Tower of Pisa
Projectile motion occurs when an object is thrown or launched into the air and is influenced only by this force.
Gravity
At the highest point of a roller coaster, what type of energy is at its maximum?
Potential Energy
What are Isaac Newton's 3 Laws of Motion?
1. An object in motion (or at rest) wants to stay in motion (or at rest) until acted on by an outside force.
2. Force = mass x acceleration
3. Every action has an equal and opposite reaction
Which of Newton’s other well known laws states that every mass in the universe attracts every other mass?
Law of Universal Gravitation
Galileo’s studies laid the groundwork for this scientist’s laws of motion and universal gravitation.
Isaac Newton
What is the optimal angle for achieving the maximum range in projectile motion (ignoring air resistance)?
45 Degrees
What type of potential energy is stored when an object is raised to a certain height?
Gravitational Potential Energy
What did Johannes Kepler discover about planetary motion?
Planets orbit the sun in an elliptical shape, rather than circular.
According to Newton, the gravitational force between two objects depends on what two factors?
Mass and Distance
What is the rate at which gravity pulls objects towards Earth?
9.8 m/s2
In the real world, projectiles don’t follow perfect parabolic paths due to what force acting in the opposite direction of their motion?
Air resistance
What kind of potential energy is stored in the rubber band of your catapult right before release?
Elastic Potential Energy
What property of an object, related to Newton’s second law, describes how difficult it is to change the object's state of motion?
Momentum
The time it takes for a projectile to reach its highest point is equal to the time it takes to do this.
Fall back to its original height (or return to the launch level)
