11 - Potential Energy for Non-contact Forces

Students, this is your 11-Try-it for today! You should take it until you are confident with your score. It focuses on vocab!

Kinetic energy

Energy of motion

Potential Energy

Stored energy. 

The object has the ability to move but hasn’t.

Gravitational potential energy

Energy stored due to position in a gravitational field, measured in joules.

Multiple Choice

Energy due to the position of an object in a gravitational field is ___

• Kinetic energy

• Noncontact Forces

• Gravitational Potential Energy (GPE)

Multiple Choice

Forces that can push or pull objects without direct touch

• Mass

• Noncontact forces

• Kinetic energy

Multiple Choice

Objects in motion have _.

• Potential energy

• Non contact forces

• Kinetic energy

Multiple Choice

To increase the GPE (gravitational potential object) of an object, you could...

• Drop the item from a tower.

• Decrease the mass of the object

• Climb higher up the tower with the object

Mass

Amount of matter in an object

Measured in grams (g)

Velocity

Speed of an object in a given direction

Measured in meters per second (m/s) or miles per hour (mph)

Multiple Choice

Speed in a given direction. Measured in meters per second (m/s) is called ____.

• Mass

• Constant

• Velocity

• GPE

Multiple Choice

When an object has the ability to move but hasn’t

• Potential energy

• Velocity

• kinetic energy

Multiple Choice

The amount of matter in an object, measured in grams.

• Mass

• GPE

• velocity

Experimental Design

You will need to know how to describe the parts of an experiment on the SWYK and the next test

Independent Variable

• This is the part of the experiment that “I change”.

• We label the x- axis (the left to right axis) on the graph with the independent variable.

• 
  

Dependent Variable

• This is the part of the experiment that changes because of the variable you changed. This is the part of the experiment that you record on your data table.

• We label the y- axis (the top to bottom axis) on the graph with the dependent variable.

Constants

• Part (s) of the experiment that stays the same.

• Accurate experiments only change one variable and keep all other variables the same. You always want a fair test.

Multiple Choice

The part of the experiment that I change is the ____

• Independent variable

• Constant

• Dependent variable

Multiple Choice

The parts of the experiment that must stay the same to get accurate results are ____

• Independent variable

• Constants

• Dependent variable

Multiple Choice

The part of the experiment that is measured and recorded as data

• Dependent variable

• Independent variable

• Mass
