Waves
What describes a longitudinal wave?
The energy of the wave moves back and forth to the wave direction.
What is an example of a Force?
Gravitational, Magnetic, Electrostatic, Friction, and air resistance.
True or false: Newton's 2 laws affect everything
True
What is the matter?
Any substance that has mass and takes up space by having volume.
What is the definition of inertia?
The tendency to resist any change in motion.
What describes a transverse wave?
Particles of the wave move perpendicularly (up and down) to the direction of the wave.
What is the definition of Energy?
The ability to do work or cause change
Who discovered the 3 laws of motion?
Sir Issac Newton.
flammability, toxicity, acidity, and oxidation.
What is the chemical Symbol for Gold?
Au
What is the lowest point in a transverse wave?
trough
What unit is energy measured in?
Joule (J)
What are Newton's 3 laws
First law: Law of inertia
Second law: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is often expressed as the equation F = ma, where F is force, m is mass, and a is acceleration.
Third law: For every action there is an equal and opposite reaction.
Colour, density, volume, and mass
What is the equation for wave speed?
Crest
What are 2 examples of contact and non-contact forces?
Non-Contact: Gravitational, Magnetic, and Electrostatic
Contact: Friction, Air resistance
True or False Newton's 2nd law of motion is the law of inertia
False
What is the definition of Chemical Properties?
a specific characteristic of a substance, like an element or a compound, relating to how it can change as a result of a reaction.
What is the smallest unit of matter?
an atom
Sound is Longitudinal, and electromagnetic is transverse.
What are 3 examples of kinetic energy and 3 examples of potential energy?
PE: Gravitational, Chemical, Nuclear, and Elastic.
KE: Electrical, Thermal, Sound, and Electromagnetic
What is an example of Newton's 3rd law of motion?
Ex: If a ball hits a wall and the ball moves back because for every action there is an equal and opposite reaction.
What are physical properties of matter? Give the definition.
characteristics of a substance that can be observed or measured without changing the substance's chemical identity
What is the bond that holds atoms together?
Chemical Bond.
