Momentum
This is equal to mass times velocity.
What is momentum?
These positively charged particles are found in the nucleus of an atom.
What are protons?
An object gains a static charge by the loss and/or gain of these.
What are electrons?
This is the unit for electric charges.
What is the coulomb?
A car with mass 100 kg is traveling 5 m/s. It has a momentum of this.
What is 500 kg m/s
Total momentum before a collision is equal to total momentum after a collision is known as this.
What is Law of Conservation of Momentum?
An atom that has gained or lost electrons is also known as this.
What is an ion?
A glass rod is rubbed by a silk cloth. It is charged due to this form of static transfer.
What is friction?
To like charges will do this.
What is repel?
As you move 2 charged particles away from one another the force between them will do this.
What is decrease?
This is the unit of momentum.
What is kg m/s?
This is partnered with the proton inside the nucleus of an atom.
What is a neutron?
These items will allow electrons to easily pass through or flow through them.
What are conductors?
These are drawn around a charged particle to represent the electric field surrounding it.
What are field lines?
A 500 kg car is traveling at 10 m/s when it collides with a stationary 350 kg car. This is the total momentum after the collision.
What is 5000 kg m/s?
Mr. Davis is running at Ryan when he jumps on him and they both tumble together forward. This is an example of this type of collision.
What is an inelastic collision?
An ion that is positively charged has done this.
What is lost electrons?
The gold leaves on this device will determine if there is a charge in an object.
What is an electroscope?
An electric field is an example of this because it has magnitude and direction.
What is a vector?
This is what occurs to the electric force surrounding a charged particle as the amount of charge is increased.
What is increase?
When involved in a crash, to lower the force being felt this should happen over time instead of instantly.
What is change of momentum?
The best conductors contain lots of these.
What are free electrons?
Lightening is example of static charge produced by this.
What is induction?
This environment will only allow those inside to interact and will not allow any outside interference.
What is a closed system?
Jerry has a mass of 50 kg and is riding his bicycle at 1 m/s. He is not paying attention and crashes into a parked car. It takes Jerry 0.2 s to come to a stop. This is the force felt by Jerry in his crash.
What is 250 N?
