what is bouyancy?
an upward force exerted by a fluid that opposes the weight of an immersed object
what is scientific notation?
easy way to write very large or small numbers
What is inertia?
A term used to measure the ability of an object to resist a change in its state of motion.
What is gravity?
9.8 m/s^2
What is kinematics?
describes motion of points, bodies and systems of bodies without considering the forces that cause them to move.
What is kinetic Friction?
When the object is moving.
0.00076
7.6x10^-4
What is newtons second law?
the acceleration of an object is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
Shortest distance between two points with direction.
Displacement
This type of friction occurs when an object is at rest and prevents it from moving.
Static Friction
.00085 in scientific notation
8 X 10-4
What is the difference between mass and weight?
Mass: is the amount of matter in an object.
Weight: is the force of gravity on the objects mass.
In the newtons second law of motion, what is the formula that relates force, mass, and acceleration?
F= ma
1.23x10^4
123120000000000
a plane accelerates from 12 m/s to 30 m/s in 3s. If the mass is 1200kg, what is the force on it?
7,200 N
a biker passes a tree at 4.5 m/s. she accelerates down the hill at a constant rate of 0.40 m/s^2 for 12s. how far does she move down the hill during this time?
83m
What is Mr. Bui's last name?

determine the mass and the weight of an 86-kg man on the moon where the gravitational field is 1/6 that of the Earth.
mass: 86 kg
weight: 140N
