Newtons
State Newton’s First Law.
An object in motion stays at motion unless acted upon by an outside force
This is the distance between two waves
What is wavelength?
What is the difference between conductors and insulators?
Conductors allow current to flow easily; insulators resist it.
What is the formula for momentum?
Momentum = Mass x Velocity
P = M x V
This quantity is the rotational equivalent of force.
What is torque?
What is the formula for Newton’s Second Law?
F = M x A
This describes how fast a wave is moving
What is frequency?
This is measured in amps
current
What happens to momentum if velocity doubles?
Momentum Doubles
This is the formula for torque.
What is τ=rF
Torque = leverage arm x Force
State Newton’s Third Law.
For every Action there is an Equal and Opposite Reaction
This describes how tall or how short a wave is
What is amplitude
This is the unit for resistance
ohms
A 5 kg object moving at 4 m/s—what is its momentum?
20 m/s/kg
The unit for torque is this.
What is the Newton-meter (N·m)?
A 2 kg object experiences a 10 N force—what is its acceleration?
5 m/s2
This is the tallest part of a wave
The opposition to the flow of electric current. It is what slows a current down or possibly stops it
resistance
A 10 kg object at rest has this momentum.
What is 0 kg·m/s
A 10 N force is applied 2 m from a pivot (perpendicular). This is the torque.
What is 20 N·m?
Give an example of action-reaction forces.
Multiple Answers Accepted
This is the shortest/deepest part of a wave
What is the Trough
A circuit has a voltage of 12 V and resistance of 4 Ω. What is the current?
3 A
This term describes the product of force and time.
What is impulse?
If the applied force doubles, this happens to torque.
What is it doubles?
