Planets
Does Pluto count as a planet?
No, in 2006 they classified Pluto as a dwarf planet.
What is a force?
A force is a push or pull.
What is Velocity?
Velocity is basically just speed with a direction involved.
What is the force that is most commonly known by children?
Gravitational force (Gravity)
Joey drove 92 miles North in 4 hours. What is his velocity?
23 mph North.
What is the planet closest to the sun?
Mercury.
What is gravity?
Gravity is the pull of an object on another object that changes when the mass of an object changes.
What is the formula for speed?
The formula for speed is the distance the object went divided by the amount of time it took to get there.
Formula:distance/time=speed
ex: 12/3=4 Speed is 4 m/s2
What is static friction?
Static friction is non-moving friction(The friction of an object that is not moving)
Sarah was driving home at 54 mph, and it would take her 8 hours to get there. How far would she have to go if she kept driving at a constant speed?
432 miles.
What is the planet that is furthest from the sun?
Neptune. (Did you read it carefully?)
What are 3 types of friction?
1.) Static Friction
2.) Sliding Friction
3.) Rolling Friction
4.) Fluid Friction
5.) Air Resistance
What are the 3 types of acceleration?
1.) Speeding up (Accelerating)
2.) Slowing down (Decelerating)
3.) Turning
What is fluid friction?
Fluid friction is friction that happens in the water or in the air.
Jayden decided to walk to the park, but it was 15 minutes away at least. Jayden walks at a constant speed of 3 mph, so he figured that he might as well run there. Since his running speed is 5 miles per minute, how long will it take Jayden to get there?
3 minutes.
What planet has the most moons?
Jupiter. It has 79 moons!
What are 4 types of forces?
1.) Normal Force
2.) Centrifugal Force
3.) Gravitational Force
4.) Frictional Force
5.) Applied Force
6.) Magnetic Force
7.) Electrostatic Force
If Jeff is going 22 meters per hour South-West, then how long will it take him to go 440 meters?
It will take him 20 hours.
What is normal force?
Normal force is the force that supports whatever object's on it.
Lynn had decided to bike 124 miles this evening, and that she would go at a constant speed of 8 miles per minute. How long would it take her to bike that far?
15.5 minutes.
What planet does the moon Titan belong to?
Jupiter.
What is Earth's gravity rate?
9.81 meters per second (9.8 mps is acceptable too)
What is the formula for acceleration?
The formula for acceleration is the final velocity subtracting the initial velocity which is then divided by the amount of time it took for the object to get there.
Formula= Final Velocity-Initial Velocity=_____/Time
Ex: 58-18=40---40/5=8 Accelereation rate is 8 m/s2
What is electrostatic force?
Electrostatic force is the push or pull of an object against another object based on its electric field.
Mallary was running to Babies R Us to get last minute stuff for her almost born son Adam. She started running at 2 mph, but then she realized that she had to be home in 15 minutes, so she sped up to 5 mph in 2.5 minutes. What was her acceleration rate?
5-2/2.5=
1.5 mph.
