Motion and Newton's Laws
This law focuses on acceleration.
What is Newton's second law?
The product of force multiplied by time
What is change in momentum?
The phenomenon of thermal energy flowing from hot to cold.
What is heat?
What is the Moon?
Electric field lines about a point charge extend outward when the charge is this.
What is positive?
This happens when a falling object's acceleration is zero.
What is terminal velocity?
In the absence of an external force, the momentum of a system remains unchanged.
What is the Law of conservation of momentum?
The temperature scale where 0 degrees is the freezing point of water.
What is Celsius?
The Coriolis force is the result of this.
What is the Earth's rotation?
Electric potential is measured in this unit.
What is volts?
The direction in which friction forces act between two objects.
What is opposite?
A collision where the objects become tangled or coupled together.
What is an inelastic collision?
When water changes to ice, water molecules do this.
What is release energy?
90% of the the atmosphere is located in this layer.
What is the Troposphere?
Electric current is measured in this.
What is ampere?
This increases as an object freely falls.
What is velocity?
This is what a bus' kinetic energy transforms to when it brakes.
What is heat?
The transfer of internal energy by electron and molecular collisions within a substance.
What is conduction?
A funnel cloud becomes this when it touches the ground.
What is a tornado?
A 10-ohm resistor carrying a current of 5 A has this voltage.
What is 50 V?
The speed of impact if a 48km/h car bumped into a car going 50km/h in the same direction.
What is 2km/h?
The force of gravity between two planets is decreased when this is increased.
What is distance?
The change of phase from liquid to gas.
What is evaporation?
These two elements make up 99% of Earth's atmosphere.
What is Nitrogen and Oxygen?
This the product of voltage divided by resistance.
What is current?
