Forces 100 Answer: Static friction (not moving), Sliding friction (opposes motion as moves), Rolling friction (objects moving with wheels), and fluid friction (opposes motion of liquids). Question: What are the four types of friction?

Forces 200 Answer: A force can set an object at rest into motion; or it can accelerate a moving object by changing its speed or direction. Question: How is motion of an object affected by force?

Forces 300 Answer: The force that acts downward toward the center of Earth. Question: What is Earth’s gravitational force?

Forces 400 Answer: The combination of an initial forward velocity and the downward vertical force of gravity causes a ball to follow a curved path. Question: What is projectile motion?

Forces 500 Answer: by acting in an opposite direction of the motion this slows down the acceleration of a falling object. Question: What is how air resistance affects the acceleration of falling objects?

Newton's 1st Law 100 Answer: The state of ___ of an object does not change as long as the net force acting on the object is zero. Question: What is motion?

Newton's 1st Law 200 Answer: A zero net force affects an object’s motion. Question: What is the object’s motion does not change.

Newton's 1st Law 300 Answer: the tendency of an object to resist a change in motion. Question: What is inertia?

Newton's 1st Law 400 Answer: Newton published a book where he introduced his laws of motion. Question: What is the book entitled Principia?
