Kinematics
This allows us to determine the motion of an object.
What is frame of reference?
This happens only if the forces are unbalanced.
What is acceleration?
The formula for work
What is w=fd?
Formula for kinetic energy
What is KE=1/2mv²
Formula to change Fahrenheit to Celsius.
What is F=1.8C+32
Formula for velocity.
What is change in distance divided by change in time? V = Δx/Δt
This is the direction of normal force.
What is perpendicular to the surface the object is on?
The formula for power.
What is p=w/t
Formula for GPE
What is PE = mgh
90 degrees Celsius in Kelvin
What is 363.15 K?
The formula for acceleration
What is Δv/Δt?
You pull on a rope with 100 N to the right. Your bestie is pulling on the rope with 75 N left. What is the net force on the rope?
What is 25 N right?
The IMA of a simple machine that exerts 100 N of force through a distance of 10 m. The machine exerts a force of 600 N and lifts the load 1.5 m.
Speed of a 0.25 kg apple when it hits the ground after falling 3.0 m from a tree.
V = 7.74 m/s^2
or 7.67 m?s^2
Would a room of 360 K be warm, cold, hot, ornfreezing?
Very hot - 90 degrees Celsius or 188 degrees Fahrenheit is almost boiling.
Formula to find displacement to find motion that moves X meters right and Y meters south.
displacement = √X²+ Y²
Objects will remain in their current state unless acted upon by another force.
What is the law of inertia? (Newton's first law)
The AMA of a simple machine that exerts 100 N of force through a distance of 10 m. The machine exerts a force of 600 N and lifts the load 1.5 m.
What is AMA = 6
On a swing, the point where the GPE is greatest and the KE is least.
What is the apex (top) of the arch of the swing?
Here, entropy (the amount of energy in a system unavailable for useful work) is at its minimum here.
What is absolute zero?
The length of time it would take you to travel 500 km if you traveled at 50 m/s? Answer should be in hours.
What is 2.78 hours?
The direction of friction.
What is opposite to the direction of motion?
AMA/IMA
What is efficiency?
Renewable organic materials
What is biomass?
The specific heat of a 75.4 g sample that is warmed 65.6 °C by adding 1187 J of energy?
What is 0.240 J/g degrees C
