What's my approach for...
A problem that involves any type of collision.
What is the Law of Conservation of Momentum?
(p_1+p_2=p_1'+p_2')
OR impulse momentum equation
The first thing you check for on any graph.
What are the axes?
The direction of centripetal acceleration.
What is towards the center?
This is always conserved in a collision in a closed system
What is Momentum
What DON’T you do when making a best fit line?
Connect the dots
A problem asking about acceleration that doesn't include any forces.
What are kinematic formulas?
The area under the curve on this type of graph is defined as work.
What is a F-d graph?
The direction of the normal force when a roller coaster is moving in a vertical circle and the cart is upside down at the top.
What is down?
This fluids equation is based on the Law of Conservation of Energy
What is Bernoulli’s Equation
What must your lab procedure end with?
Repeat with multiple trials (changing one variable)
A problem that has an object with several forces acting on it.
What is draw a free-body diagram then determine the net force formulas?
Method to determine the displacement from a velocity-time graph.
What is determine the area under the line?
When a skater pulls their arms in while spinning, this happens to the rotational inertia.
What is decreases?
In a closed system a moon travels in an elliptical orbit. What explains why it speeds up as it gets closer to the planet?
Law of Conservation of Angular Momentum
What do you do to start a lab procedure question?
Write an equation
There is a projectile with angles
Make an xy chart
where
vx=vcos(theta)
vy=vsin(theta)
A straight horizontal line on a velocity-time graph means the velocity is this.
What is constant?
The relationship between the force of attraction and the distance between two objects.
What is
F_Gpropto1/r^2
This has to be zero for energy in a system to be conserved
What is work?
Or, what is friction?
What must you include to get full points on the graph you plot?
Labels with quantities and units
A problem involving a cart moving down a ramp and colliding with another cart at the bottom of the ramp. (note: two parts)
What is the Law of Conservation of Energy THEN the Law of Conservation of Momentum?
Two things you can determine from a displacement vs time graph for an object in SHM.
What is the period (or frequency) and the amplitude (or maximum displacement)?
Equation for gravitational potential energy of an object in space?
UG = -Gm2m2/r
Conservation of this quantity is a direct result of Newton’s 3rd Law
What is momentum?
What is the main thing to include when you have to write a lab procedure?
Vary one quantity, measure another
