Energy
A quantity that corresponds to the ability an object has to be in motion, or the ability an object has to cause other objects to be in motion.
What is energy? OR
What is mechanical energy?
The two variables that are multiplied to calculate momentum.
What are the mass and the velocity?
Objects that travel along a circular or curved path experience this type of rate of change in position over time.
What is speed?
This type of velocity is found when an object experiences an acceleration.
What is instantaneous velocity?
Our lab room number
What is N.B. 3.65?
The unit used when discussing quantities of energy.
What is a joule?
The type of collision where the two objects will travel at the same velocity after the collision.
What is a perfectly inelastic collision?
Centripetal force is considered this other type of force.
What is a net force?
In 2D motion, in this component the object experiences constant v velocity.
What is the horizontal component?
This river is out our windows.
What is the Hudson River?
A type of force where energy is not lost.
List two examples of this type of force.
What is a conservative force?
1. Gravitational force
2. Spring force
The type of collision where all energy is conserved throughout the collision.
What is a perfectly elastic collision?
It is easier to move an object along a circular path with a shorter radius.
TRUE or FALSE
FALSE
An object can be experiencing a net force of 0N and still have a non-zero velocity.
TRUE or FALSE
TRUE
The 5 required components to *most* of your lab reports.
What are the:
1. Coverpage
2. Apparatus/Setup
3. Procedure
4. Data
5. Conclusion
A type of work that can be done by a spring.
What is elastic potential energy?
The type of collision where the two objects will travel at the same velocity before the collision.
What is a reverse perfectly inelastic collision?
The amount of time it takes to complete one full revolution.
What is the period (T)?
Spring force can work in any direction. It serves to restore the spring to this.
What is the equilibrium position?
The percentage of your total grade that lab makes up.
What is 40%?
The rate at which energy is transferred from one object to another.
What is Power (J/s)?
The type of collision can energy be "lost" due to friction or heat air resistance.
What is an arbitrary elastic collision?
This is the formula for centripetal acceleration.
ac = (m * v2)/r
This is the long-form formula for gravitational force.
Fg = (G m1 m2) / r
