Scientific Method
This is an educated guess about the results of an experiment.
HYPOTHESIS
This word refers to how far an object has traveled
DISTANCE
What are the 3 ways you can have a change in velocity?
Increasing speed, decreasing speed, and change in direction
This is the energy an object has when it is stationary.
POTENTIAL ENERGY
What is the unit for force?
Newton
This is the variable of the experiment that you change in order to see different results.
INDEPENDENT VARIABLE
A car travels 50 miles in 10 minutes. What was the car's speed?
5 miles per minute
What is the difference between speed and velocity?
VELOCITY INCLUDES DIRECTION
Name one type of kinetic energy.
MECHANICAL, ELECTRICAL, SOUND, ELECTROMAGNETIC, or THERMAL
There are 2 people that are pushing and pulling a box to the left. Person 1 pushes with a force of 15 Newtons. Person 2 pulls with a force of 12 Newtons. How much force is acting upon the box and in what direction?
27 Newtons to the LEFT
This is the step of the scientific method where you run the tests and collect data.
EXPERIMENT
A horse gallops 6 miles in 1.5 hours. What was the horse speed?
4 miles per hour
A car travels up a hill going 40 miles per hour. Then, it travels down the hill going 75 miles per hour. What is the car's acceleration?
Increasing (speeding up) by 35 miles per hour.
A ball rolling down the hill has a potential energy of 2.5 Joules and a kinetic energy of 8.5 Joules. What is the ball's mechanical energy?
11 Joules
There are 2 people pulling on the box in OPPOSITE directions. The person pulling to the left pulls with a force of 42 Newtons. The person pulling to the right pulls with a force of 26 Newtons. What direction is the box moving and with how much force?
16 Newtons to the left
This is the variable that is the result or the change in response to the independent variable.
DEPENDENT VARIABLE
A plane, with a speed of 300 miles per hour, travels for 3 hours. How far did it travel?
900 miles
A rollercoaster cart goes down a hill at 80 miles per hour. Then it travels through the loop with a speed of 65 miles per hour. What is the cart's acceleration?
Decreasing (slowing down) by 15 miles per hour.
294 Joules
What is the density of a rock that weighs 15 kilograms and has a volume of 7.5 cm3?
2 kilograms per cm3
This is the step of the scientific method where you come up with an answer after you have analyzed the data.
A dog runs down the street with a speed of 5 miles per hour. It ran a total of 15 miles. How long did the dog run for?
3 hours
A person running a marathon run the first 16 miles in 4 hours. Then, they run the last 10 miles in 5 hours. What is the person's acceleration?
Decreasing (slowing down) by 2 miles per hour.
A rollercoaster cart that weighs 60 kilograms rolls down a hill with a speed of 30 meters per second. What is the cart's kinetic energy?
27,000 Joules
A cube with a width of 4 cm has a weight of 16 grams. Calculate the density. Will it float in water which has a density of 1 g/cm3?
16/64 g/cm3 or 1/4 g/cm3
IT WILL FLOAT
