Newton’s Laws (SC.912.P.12.3)
This law explains why objects at rest stay at rest.
What is Newton’s First Law?
This describes how fast position changes.
What is speed?
This is energy of motion.
What is kinetic energy?
This is mass times velocity.
What is momentum?
This is the distance between wave crests.
What is wavelength?
This diagram shows all forces acting on an object.
What is a free-body diagram?
This graph has a slope equal to velocity.
What is a position vs. time graph?
This type of energy depends on height.
What is gravitational potential energy?
This law states total momentum before equals total momentum after.
What is conservation of momentum?
This measures how many waves pass per second.
What is frequency?
When net force equals zero, an object is in this condition
What is equilibrium?
An object accelerates at 2 m/s² for 3 s starting from rest. This is its velocity.
final velocity = initial velocity + (acceleration x time)
What is 6 m/s?
Work done when a 10 N force moves an object 5 m.
W=Fd
What is 50 J?
Two objects stick together after a collision. This type of collision is described.
What is inelastic collision?
This equation relates voltage, current, and resistance.
What is Ohm’s Law?
A 5 kg object has a net force of 20 N. This is its acceleration.
What is 4 m/s²? a=f/m
This quantity is the slope of a velocity vs. time graph.
What is acceleration?
This measures how fast work is done.
What is power?
A 2 kg object moving at 3 m/s has this momentum.
momentum (p) = mass x velocity
What is 6 kg·m/s?
Increasing resistance while voltage stays constant causes this to decrease.
What is current?
A book pushes on a table; the table pushes back with equal force. This law explains it.
What is Newton’s Third Law?
An object is thrown upward. At the highest point, this is its velocity.
What is 0 m/s?
Final velocity = initial velocity - (gravity x time)
A machine does 200 J of work in 4 seconds. This is its power.
What is 50 W?
Power = work / Time
Increasing the time of impact reduces this quantity during a collision.
What is force? (Impulse-momentum theorem)
A circuit has 12 V and 3 A. This is the resistance.
Resistance (R) = voltage (V) / current (I)
What is 4 Ω?
