This scientist conducted experiments with falling objects to conclude that all objects in a vacuum would fall at the same rate.
Who is Galileo?
The total length of a path traveled by an object.
What is 4.2 km/h?
The motion of an object that is falling due to gravity alone.
What is free fall?
A type of measurement consisting of only magnitude.
What is a scalar?
This person developed the first truly mathematical model of motion with his three laws of motion.
The change in an object's position.
What is displacement?
A tractor pulls a wagon with feed from 100. meters east of the barn to 200. meters west of the barn in 8 minutes (480 seconds). Calculate the velocity of the tractor in m/s.
What is 0.63 m/s west?
A property of a moving system that is equal to its velocity multiplied by its mass.
The curved path of a projectile.
What is the trajectory?
The most current model of motion dealing with the behavior and motion of subatomic particles.
What is quantum mechanics?
The distance traveled in a given amount of time.
What is speed?
A bird is flying at 12 km/h south. The wind is blowing at 35 km/h east. Calculate the resultant velocity of the bird.
What is 28 km/h southeast?
What is projectile motion?
A measurement that includes both a magnitude and direction.
What is a vector?
This Greek philosopher believed objects moved as they did because it "was their nature" to do so.
Who is Aristotle?
The rate at which an object's position changes.
What is velocity?
A motorcycle traveling north slows from 26 m/s to 8 m/s in 15 seconds. Calculate the acceleration of the motorcycle.
What is 1.3 m/s2 south?
The study of motion.
What is mechanics?
An object's does this if the acceleration is in the opposite direction of the object's motion.
What is slows down?
These early scientists worked together to study the motion of planets, leading to identifying the three laws of planetary motion.
Who are Brahe and Kepler?
The change in an object's velocity in a given amount of time.
What is acceleration?
A cliff diver takes 2.25 seconds to hit the water below. Calculate the diver's final velocity as he enters the water.
What is 22.1 m/s down?
The study of how things move.
What is kinematics?
In circular motion, centripetal force and acceleration are always in this direction.
What is toward the center of the circle?
