What is velocity
The total distance travelled by a dog who wanders 6m East, 3m North, then 2m South.
6m + 3m + 2m = 11m travelled
He developed theories of gravitation and mechanics, and invented differential calculus
Who is Sir Isaac Newton
Light from the Sun takes approximately this amount of time to reach Earth
What is 8 minutes
This electronic device is used to measure an object's speed in real time
What is a photogate
This quantity can be represented by finding the area under the curve on a velocity vs time graph
What is displacement
This variable is a constant 9.81 m/s2, typically represented by the letter "g"
What is the acceleration due to gravity?
In the 1630s, this scientist showed that all freely falling bodies have the same constant acceleration.
Who is Galileo Galilei?
Physics is said to have been discovered in this century
What is the fourth century
This electronic device is used to measure an object's displacement in real time
What is a motion sensor
What is the slope
The acceleration of a car that goes from 30 m/s to 50 m/s in 5 seconds.
50 - 30 = 20 m/s
20/5 = 4m/s2
Who is Albert Einstein?
What is matter?
Athletes may use this concept of physics to determine the correct angle and speed to throw a basketball
What is projectile motion
A quantity that can be described completely using magnitude and a unit
What is a scalar
An object is launched from the ground and eventually returns to the ground. This angle will ensure it reaches its maximum horizontal displacement.
45 degrees
Before Isaac Newton, this philosopher published his own theory of motion
Who is Aristotle?
Mr Leto named his cat after this ancient astronomer.
Who is Tycho Brahe?
Robotic and mechanical systems require the calculation of these equations to express the relationship between control and command variables
What are kinematic equations
Distance is to speed as displacement is to _____
What is velocity
The displacement of a bike that starts from rest and reaches a speed of 8 m/s after 5 seconds
s = (0+8)*5/2
s = 20m
Who is Johannes Kepler?
This is considered Earth's only natural satellite
What is the Moon?
Radar guns are used by police offices and in professional sports to measure this physics variable
What is speed
