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?
The relationship between speed, distance and time
What is speed = dist/time or dist*time=speed
Visible light rays allow you to see colors that are reflected or absorbed?
What is reflected?
Waves will travel only as long as it has ________ to carry
What is energy?
This type of energy describes motion
What is Kinetic energy?
Name the two types of waves
What are transverse and longitudinal
You drive for 500m then turn around and ride back to the starting point, the distance traveled?
What is 1000m?
The difference between speed and velocity
Velocity is speed with direction/vector
Wave A has more energy that wave B. Which has a smaller wavelength?
Wave A (smaller wavelength, more energy)
A huge rock sitting on top of a mountain is this type of energy
What is Potential Energy?
The attractive force that acts on all objects everywhere on earth all the time
What is gravity?
An object travels 18m in 3 seconds. What is it's speed?
What is 6m/s
When you travel 500m, then go back 200m, what is the displacement?
What is 300m?
Sound travels in a __________ wave
What is longitudinal?
You know something is moving by comparing it to this
What is a reference point?
The equation for Newton's 2nd law
What is F = m*a?
The acceleration of an object due to Earth's gravity
What is 9.8m/s/s
These rays are used for medical imaging
What are gamma rays?
Light, radiation, and sound waves are all this type of energy
What is Electromagnetic or EM?
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 500 kg?
m= F/a = 10,000 / 20
m= 500 kg
From rest, an object reaches 8m/s in 2 seconds. it's acceleration is...
What is 4m/s/s?
The force that would be less if you were on the moon
What is weight?
When you push a slinky together and then stretch it out, you have this type of wave
What is longitudinal (compression) wave?
