Describing Motion
What are the two parts that make up velocity?
Speed and direction
What are balanced forces?
Forces acting on the same object that are the same size and acting in opposite directions (forces that cancel out)
Inertia is a property of matter. Because of inertia, an object's motion won't change unless what?
An unbalanced force is applied
What form of energy does a speaker give off?
Sound (vibrations)
What are the three types of acceleration?
Name 3 different forces.
If you apply the same amount of force to an object in the same direction, but decrease its mass, how will its motion change?
It will go faster and further
We watched a video that described 4 types of friction. Name at least 2 of them.
Sliding, rolling, static, fluid
Speed equals what divided by time?
Distance
One person is pushing 100 N on a box to the left. Another person is pushing that same box 80 N to the right. What is the net force?
20 N to the left
What is the difference between mass and volume?
Mass is the amount of matter something has; volume is the amount of space it takes up
What is the difference between quantitative and qualitative?
Quantitative uses numbers (describes quantities); qualitative uses words (describes qualities/properties)
