Kinematics is...
a branch of Newtonian mechanics that deals with the description of motion.

Give an example of a Kinematics problem describing motion in only one dimension
Dropping objects problem

Give an example of a Kinematics problem describing motion in two dimensions
Projectile motion problem

Define displacement.
Is it a scalar or vector quantity?
SI units
an object in motion experiencing a change in its position in space undergoes displacement.
It's a vector quantity, connecting in a straight line the objects initial and final positions.
m

Define velocity.
Scalar or vector?
SI units
Rate of change of displacement in a given unit of time.
Vector.
m/s

Define speed.
Scalar or vector?
SI units
 Rate of actual distance traveled in a given unit of time.
 Scalar.
 m/s

Define acceleration.
Scalar or vector?
SI units
 Rate of change of velocity over time.
 A~ results from application of force(s).
 Vector
 m/(s^2)


On MCAT when you see Force, think
 Acceleration
 And when you see Acceleration, think Force.
 MCAT limits kinematics problems to those involving motion with constant acceleration.

Define and name examples of linear motion problems.
What are directions of v and a in linear motion?
Motion along a line.
Along a line (both v and a)
 Examples:
 (1) motion along a vertical path
 (2) motion along a horizontal path
 (3) motion along an inclined surface or ramp

_{Summary of kinematics equation (5 of them)
}
Δx=1/2*(v0+v)*t = v(bar)*t
v(bar) = 1/2*(v0+v)

Projectile motion is...
Give an example.
...motion that follows a path along two dimensions.
Two dimensions (usually horizontal and vertical) are independent of each other and must be analyzed separately.
E.g.: cannonballs (pushka, zarbazani), baseballs, bullets...
