Gravity and Inertia
Forces
Waves
100
This is the metric unit for length.
What is METER?
100
This is the equation for speed.
What is DISTANCE/TIME?
100
The resistance to change in motion.
What is INERTIA?
100
The definition for force.
What is PUSH OR PULL?
100
Half the height of a wave.
What is AMPLITUDE?
200
An object is in motion if it changes position relative to this.
What is a REFERENCE POINT?
200
You calculate this by dividing the total distance by the total time.
What is AVERAGE SPEED?
200
A bus and a car are both moving at the same constant speed. If a deer jumps out in the middle of the road ahead the bus has to begin braking sooner because it has more of this.
What is the INERTIA.
200
The sum of all forces acting on an object.
What is NET FORCE?
200
When two waves meet up peak to peak and the waves are amplified.
What is CONSTRUCTIVE INTERFERENCE?
300
Draw a graph of motion (distance vs. time) that shows constant speed.
300
This is speed with direction.
What is VELOCITY?
300
This is the reason planets have elliptical orbits.
What is GRAVITY from a central mass (the sun)?
300
When the net forces acting on an object are zero, the forces are...
What is BALANCED?
300
This is why we cannot hear sounds in space.
What is BECAUSE SOUND WAVES NEED A MEDIUM THROUGH WHICH TO TRAVEL?
400
Draw a graph of motion (distance vs. time) that shows an object at rest.
What is a STRAIGHT LINE with NO SLOPE, like this: ------------------------------------------>
400
The average speed of a bicycle that traveled a total of 100 meters in 10 minutes.
What is 10 METERS PER MINUTE?
400
This type of telescope can receive signals from space during ant type of weather.
What are RADIO TELESCOPES?
400
This is the force of gravity on an object's mass.
What is WEIGHT?
400
This is why a plum appears purple.
What is BECAUSE IT REFLECTS PURPLE WAVELENGTHS AND ABSORBS ALL OTHER COLORS?
500
Draw a graph of motion (distance vs. time) that shows acceleration.
What is a SLOPE getting STEEPER, like this: http://www.physics247.com/physics-homework-help/004o.jpg
500
The average speed of a car that traveled 10 meters in 10 minutes, then stopped for 20 minutes, then continued 30 meters in 10 minutes.
What is 10 METERS PER MINUTE?
500
This is why an unwrinkled piece of paper fall slower than a wadded up piece of paper if dropped from the same height?
What is because the unwrinkled paper has more SURFACE AREA and therefore more AIR RESISTANCE?
500
This type of friction acts on objects falling through the air.
What is AIR RESISTANCE?
500
A filter that changes the color of light passing through it has to be this.
What is TRANSLUCENT?
