What is distance an object travels over time called?
Speed
What is the combination of all forces called?
Net force
True or False: An object at rest will not stay at rest.
False
Acceleration
What is the push or pull on an object? Give an example.
Force. Examples vary.
If force on an object is unbalanced, what will happen to the object?
It will move
What is the equation to solve for Force?
True or False: A speed vs. time graph can be used to analyze the motion of an accelerating object.
True
What is inertia? Does an object with a bigger mass have more or less inertia?
What is the force that two surfaces create when they rub against each other called?
Friction
True or False: The Law of Universal Gravitation states that two objects that have mass will attract each other.
True
Which of the following is an example of acceleration:
A. Standing Still
B. A bird landing
C. A car slowing down for a stop sign
D. an airplane taking off
D. An airplane taking off
What's the difference between speed and velocity?
Speed: Distance over time
Velocity: Distance over time WITH direction
A ball is getting pushed 10 N to the left and 3 N to the right. What is it's net force?
7 N left
Name a type of friction and give an example
Sliding, Fluid, Static
Ty throws the football at a speed of 30 meters per second to Makari. Makari catches the ball in 3 seconds. What is the football's acceleration?
10 m/s2
What's the difference between mass and weight?
Mass: amount of matter
Weight: amount of gravity
Give an example of an object experiencing a net force of zero:
An bowling ball is accelerating at 2 m/s2 due to being pushed at a force of 4 N. What is the bowling ball's mass?
2 grams
Explain how the mass of an object affects acceleration. Use the word inertia.
Objects with less mass are able to accelerate quicker due to having less inertia
