Newton's Laws
What is Newton's first Law?
An object at rest will remain at rest, or an object in motion will remain in motion, unless acted upon by an unbalanced or balanced force; this is also known as inertia.
What is the formula for wave speed?
v = fλ.
What is the definition of a molecule?
Two or more atoms held together by a chemical bond.
What is the name of this symbol? --> Hz
Hertz.
What is a state of matter in which the volume is definite but the shape is not?
Liquid.
What is Newton's second Law?
The acceleration of an object depends on the mass of the object and the amount of force applied.
What is a wave with compressions and rarefactions called?
A longitudinal wave.
What is the definition of a compound?
A pure substance made up of two or more different types of atoms joined by chemical bonds.
What is the name of this symbol? --> J
Joules.
What is the definition of Gravity?
A force of attraction between objects due to their mass.
What is the formula for Newtion's second Law?
F=ma
Imagine shaking a rope up and down. What wave would that be?
A transverse wave.
TRUE or FALSE, amorphous means a substance in which the particles are arranged in a very specific, repeating order.
FALSE.
What is the chemical formula for force?
F = ma. (Force = Mass x Acceleration)
What is the process of a gas turning into a solid?
Deposition.
What is Newton's third Law?
All forces between two objects exist in equal magnitude and opposite directions.
Name all the points on a transverse AND longitudinal wave. (Extra 50 points if you label it on a whiteboard.)
Transverse: Rest Position, Through, Crest, Amplitude, Wavelength.
Longitudinal: Rest Position, Rarefaction, Compression.
What is the molecular structure of water atoms? (Extra 25 points if you can draw it on a whiteboard.)
Two Hydrogen atoms (H), and one Oxygen atom (O).
What is the chemical formula for gravitational potential energy? (GPE)
GPE = MGH. (Gravitation Potential Energy = Mass x Gravity x Height)
Name 5 different forms of energy.
Chemical, Mechanical, Thermal, Electromagnetic, Sound, Electrical, Elastic, Nuclear.
If I have a volleyball with a mass of 9 oz and hit it with a force of 63 N, how much is it accelerating?
7 m/s. (63/9=7)
What is the wave speed of my rope if I am moving it with a frequency of 98 Hz and it has a wavelength of 14?
7 m/s.
What is the difference between an atom and an element?
An element can't be separated into simpler substances by chemical means. An atom is the smallest unit of an element that has the chemical identity of that element.
What is Ag on the periodic table? (Extra 15 points if you can tell me what Au is on the periodic table.)
Ag = Silver. (Au = Gold)
What is the equation for kinetic energy?
KE = 1/2 x M x V². (Kinetic Energy = 1/2 x Mass x Voulume2)
