Kinematics/ forces
The formula for calculating the average velocity of an object
What is v = (Δx)/t ?
This is true about change in energy when there is no air resistance or friction?
What is Δ E =0?
This is the equation for momentum
What is p = mv?
This is the distance traveled around part of a circle
What is arc length?
FINAL JEOPARDY:
A bicyclist is riding at an initial linear velocity of 7.5 m/s and accelerates to a velocity of 10 m/s over 5 s. If the wheels on the bike have a radius of 0.343 m, what is the angular acceleration of the bike wheels?
What is 1.46 rad/s?
ΣF = m x a
What is Newton's Second Law of motion?
This is the gravitational potential energy of a 2 kg object is dropped from a height of 10 m (use 10 for gravity)
What is 200 J?
Change in kinetic energy is 0 in this type of collision
What is an elastic collision?
This value becomes omega (ω ) when describing rotational motion
What is velocity?
These are two examples of things that oscillate
What are springs and pendulums?
The kinematic equation that tells us final velocity if we aren't given time
What is the 3rd kinematic equation?
This is the name of this equation W = Δ K
What is the work kinetic energy theorem?
This type of collision occurs when two objects stick together
This is the amount of radians in a circle
2 π
These are two important things we can see on a SHM graph
What are amplitude and period?
This is a contact force that is perpendicular to the surface an object is on and prevents objects from sliding through eachother
What is Normal Force?
This is the kinetic energy of a 5 kg object moving at 5 m/s
What is 62.5 J?
This is conserved in all types of collisions
What is momentum?
This causes a change in an object's rotational motion
What is torque?
This force has x and y component when objects are on inclines
What is force of gravity?
These are the forces we consider that do work on an object
These are the two equations for impulse
What is Δ p = mΔ v and Δ p=FΔ t?
These are the two types of motion an object must have in order to roll
What are linear and rotational?
This is the density of water
What is 1000 kg/ m^3?
