What happens to the force of gravity when one objects mass doubles?
The force of gravity also doubles
100
This law states that the total energy of an isolated system remains constant, regardless of the processes occurring within the system.
What is the law of conservation of energy?
100
This term describes the number of waves passing a point in one second.
What is frequency?
100
In Kepler's Third Law, the orbital period is typically measured in these units.
What are years?
100
This is the term for the distance traveled by an object divided by the time it took to travel that distance.
What is speed?
200
What happens to Kinetic Energy when the velocity of an object increases by 8 times?
The kinetic energy increases by 64 times
200
This type of energy is due to an object's motion
What is kinetic energy?
200
The phenomenon where sound waves change frequency due to the motion of the source or observer is called this
What is the Doppler effect?
200
Kepler's First Law states that the orbit of a planet around the sun is in this shape.
What is an ellipse?
200
The rate of change of velocity with respect to time is known as this.
What is acceleration?
300
What happens the the force between two charges when the charge of one particle increases by 8 times and the charge of another decreases by 1/4?
The force between the charges doubles
300
This form of energy is stored in an object as a result of its position in a gravitational field.
What is gravitational potential energy?
300
Sound waves are this type of wave, meaning they oscillate parallel to the direction of propagation.
What are longitudinal waves?
300
According to Kepler's Second Law, when a planet is closer to the sun, it moves at this speed compared to when it is farther.
What is faster?
300
When an object reaches its maximum height in free fall on Earth, its velocity is this and its acceleration is this.
Velocity is zero, acceleration is 9.8m/s^2
400
What happens to the force of gravity between two objects when the distance between them increases by 5 times?
The force of gravity decreases by 1/25
400
An archer shoots an arrow straight up with 500J of Kinetic Energy, how much and what type(s) of energy does the arrow have at the top of its movement? DON'T FORGET UNITS
500J of Gravitational Potential Energy
400
Light waves are this type of wave, meaning they oscillate perpendicular to the direction of propagation.
What are Transverse Waves
400
This planet travels the fastest around the Sun.
What is Mercury?
400
What can we say about the velocity of this object from its Distance-Time graph?
The object has no velocity, it is not moving.
500
What happens to the force of gravity between two objects when the mass of both objects increase by 10 times and the distance between them also increases by 10 times.
Force of gravity doesn't change
500
A 10kg object is dropped from 10m high. How much Kinetic Energy does it have right before it hits the ground?
1000J of Kinetic Energy
500
This phenomenon occurs when light waves bend as they pass from one medium to another.
What is refraction?
500
Using this Velocity-Time graph we can determine the acceleration of the object to be...
10m/s^2
