Mineral
What is the hardest mineral on Mohs Hardness Scale?
What type of energy depends on the relative position and its mass.
Potential Energy.
When the forces acting on an object are unbalanced, what are two possible reactions of the object?
Change in direction and /or change in speed.
What is the formula for average speed?
Average Speed = distance/time
What is the process of determining what an unknown mineral is?
Use Luster, Streak, Color and Hardness to identify the mineral with all available charts and graphs.
What are the identifiable properties of minerals.
Luster, streak, color, and hardness.
What energy begins increasing the moment a person releases the pebble from the slingshot.
Kinetic energy.
When the forces of an object are balanced then...
no change in speed or direction happens. The motion remains constant.
The distance from Dallas to El Paso is 650 miles. From El Paso to Phoenix is 430 miles, and from Phoenix to Los Angeles is 370 miles. What is the total distance from Dallas to Los Angeles?
1, 450 miles.
What energy is stored energy based on its elevation and its mass.
Potential energy.
Talc 1 Gypsum 2 Calcite 3 Fluorite 4 Apatite 5 Orthoclase 6 Quartz 7 Topaz 8 Corundum 9 Diamond 10
Which minerals will scratch Fluorite, but will NOT scratch Quartz.
Apatite and Orthoclase?
What is happening to potential and kinetic energy when a boulder starts rolling from the very top of a hill toward the bottom.
Potential Energy begins transferring into Kinetic Energy.
When a plane is ascending, what is happening with the Force of Lift and the Force of Gravity?
The forces are unbalanced because the Force of Lift is greater than the Force of Gravity.
A perfect square has 4 sides that are all the same length. One side is 30 inches long. What is the total distance around the square?
120 inches.
What is the average speed from Texas to New York by car, with a distance of 1,550 and 30 hours on the road.
51.7 mph.
What is the range of the Mohs Scale of Hardness for minerals?
10
The greater the speed something has the...
greater kinetic energy it has.
A center fielder throws a baseball straight to the pitcher, then the pitcher throws the baseball straight to home plate. What is happening with the speed and direction of the baseball after leaving the pitchers hand?
The ball will increase in speed in the same direction.
Students ran around a perfectly square field with each side equalling 200 feet. It took them 5 minutes to run around the field. What was there average speed around the field?
160 ft/minute.
What is the definition of Ascending?
Going up or increasing its relative position to the Earth.
Increasing elevation.
What is a mineral that has a Glassy luster, Colorless Streak, clear in color, and registers a hardness of 10 on the Mohs Hardness Scale.
A Diamond.
What happens to kinetic and potential energy when a train travels up a hill?
Kinetic energy decreases as it slows down and Potential Energy increases as its elevation increases.
What force causes the car driving around the race track to slow down to a stop?
The force of friction.
Going up hills, unsmooth terrain, and wind blowing in the face of a skateboarder will all change his average speed in what way?
They will decrease the average speed.
What is an Equilateral Triangle.
A triangle with three equal sides.
