Physics of Motion
This is the unit for force
What is a Newton?
This term describes the amount of matter in an object
M=W/G
What is mass?
This is a single disturbance which carries energy through a medium or through space
What is a Pulse?
What does the h stand for in the formula E = hf
What is Planck’s Constant?
Forces occurring between objects and the surfaces they are on
What is friction?
This type of energy describes motion
What is Kinetic energy?
This is the term for the Maximum speed reached by a falling object
What is terminal velocity?
These are waves that do not require a medium in order to travel.
What are Electromagnetic Waves?
Light behaves like both of these.
What is waves and particles?
An athlete runs around a track that is 100 meters long three times, then stops. What is his total distance traveled?
What is 300 m?
The acceleration due to gravity
What is 9.81 m/s2
The attractive force that acts on all objects everywhere all the time
What is gravity?
The shift in a wave’s observed frequency due to relative motion between the source of the wave and the observer.
What is the Doppler Effect?
What is empty space.
The mass of an object that is traveling at 20m/s2 and has a force of 10,000N
What is 500kg?
M= 10,000 / 20
M= 500kg
According to Newton’s second law of motion, force is equal to mass times_________.
What is acceleration?
The equation for total (net) force
What is F = m*a?
This is the type of reflection typically observed off pieces of paper.
What is Diffuse Reflection?
When an electron is in the n = 1 level in a hydrogen atom it is this.
What is the ground state?
A plane moves with a velocity of 63.5 m/s at 32 degrees South of East. Calculate the difference between the plane's horizontal and vertical velocity components in km/h.
72.8 km/h
The distance a car travelled if it drove at 40 m/s for 30 minutes
What is 72 km?
D = v*t = 40 m/s * 1800 s
D= 72,000 m = 72 km
The mass of an object that is traveling at acceleration of 20m/s2 and a force of 10,000N
What is 500kg?
M= F/a = 10,000 / 20
M= 500kg
This remains constant as an electromagnetic wave refracts into a new medium.
What is frequency?
Instead of using kilograms for masses of atoms scientist use this.
What is the universal mass unit?
A bear, searching for food wanders 35 meters east then 20 meters north. Frustrated, he wanders another 12 meters west then 6 meters south. Calculate the bear's displacement.
26.93 m, 31.3 degrees NORTH of EAST
