Speed
What can speed NEVER be?
Speed can NEVER be negative.
How is velocity different from speed?
It shows direction
Define Newton's 1st Law
Object in motion remains in motion unless acted upon by oppositional force. Object at rest will remain at rest unless acted upon by external force.
What is the equation that shows the relationship for Newton's 2nd Law?
F = M * A
Dropping a ball and it bouncing back up is an example of what law?
Newton's 3rd Law
Define speed
How fast something is going at a specific moment
True or False, Velocity can be negative.
True!
What are some examples of external forces that would stop a car from moving?
Gravity, friction, air pressure, obstacle in the way etc...
What is our Force if the Mass is 5 kg and our Acceleration is 10 m/s
50
What is my favorite football team?
Green Bay Packers
What is acceleration?
The change in speed over time
In relation to an X and Y axis, what would make our velocity negative?
Moving left and/or down along our axis
What are the external forces stopping a soccer ball from rolling forever on grass?
Gravity and friction
What equation would we use if we wanted to solve for Acceleration?
Acceleration = Force / Mass
Define Newton's 3rd Law
For every action, there is an equal and opposite reaction
How are speed and acceleration different?
Speed is how fast you are going at a specific moment, acceleration is the change in speed. Can have different values.
Can speed and velocity be the same value?
Yes.
Where could we best see Newton's 1st Law in action?
In space.
What equation would we use if we wanted to solve for Mass?
Mass = Force / Acceleration
Define Newton's 4th Law
There is no 4th Law, there is only 3 Laws.
How do we calculate speed?
Distance / Time
When are speed and velocity not the same value?
Speed is always positive so if you are moving in a backwards direction from the origin, your velocity will be negative to indicate that direction.
In the process of launching something in our trebuchet, what is a good example of Newton's 1st Law?
The projectile continuing on after the long arm has stopped moving.
Solve for the Mass given the following: Acceleration is 25 m/s and the Force is 500 N.
20 kg
What subject did I get my Bachelor's of Science in?
Biology
