# Physics Vocab - 2022

Force A push or a pull that changes an objects motion
Mass The amount of matter that makes up an object - how heavy an object is
Acceleration When an object changes its motion in a certain direction
Friction The force in the opposite direction of a moving object when two objects are in contact
Newtons First Law of Motion An object will not change its motion unless a force acts on it
Newtons Second Law of Motion An objects force can be calculated by multiplying its mass x acceleration. F = M x A.
Newtons Third Law of Motion If one object puts a force on another object, the second object exerts a force of equal strength in the opposite direction
PHEOC A template that we can use to do a scientific investigation
P - PHEOC Problem - what we need to solve or investigate in the lab
H - PHEOC Hypothesis - our educated guess to the answer or solution to the problem we are investigating. What we think the results are going to be
E/O - PHEOC Experiment/Observation - our tests that we run to solve the problem and the data that we collect
C - PHEOC Conclusion - The answer to the problem or the end result of the investigation
CER Claim - Evidence - Reasoning
C - CER Claim - the answer to the question
E - CER Evidence - the data that we use to support our claim
R - CER Reasoning - the "why" to our claim. The reason that our claim is correct
Kinetic Energy The type of energy that a moving object has
Kinetic Energy Equation KE = 0.5 x mass x velocity^2
Potential Energy The energy that an object stores due to its position or stress

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
