Lecture 1
Point-like particles
Momentum (product of the mass of a particle and its velocity, it’s a vector quantity &
Newton’s 2nd law states the rate of change of momentum is equal to the force acting
on the particle)
Impulse (quantity of the effect of force acting over time to change an objects
momentum)
Lecture 2
Internal and external interactions (in own group or between groups)
Centre of mass (position defined relative to an object or system of objects due to
mass)
Inertial reference frame (motion of particle isn’t subject to forces in a straight line at
constant speed)
Conservation of momentum (momentum doesn’t change in an isolated collection of
objects)
Potential energy (energy stored in object)
Kinetic energy (energy because of its motion)
Conservation of energy (energy in closed system remains constant)
Lecture 3
Energy Graphs (potential energy of an object regarding position & tells you about the
motion of the object)
Gravitational energy graph (area under the graph between any point and the f-axis is
the gravitational energy at this point)
Graph of interactions (displays the levels of one variable on the X axis and has a
sperate line for the means of each level of the other variable)
Cross product (multiply the corresponding values in each vector and adding them
together, (a1 * b1) + (a2 * b2) ….
Work (measure of energy transfer that occurs when an object is moved over a
distance by an external force)
Lecture 4
Newton’s 1st law of motion (body at rest or at constant speed will remain so unless
it’s acted upon by a force)
Newton’s 2nd law of motion (rate of change of momentum is equal in magnitude and
direction to the force imposed on it -> F=m*a)
Newton’s 3rd law of motion (Fa = -Fb)
Average vs. instantaneous velocity (change in position over time while instantaneous
is velocity at a single point in time and space as calculated by the slope of the tangent
line)
Classification of forces (Tensional, Spring, Normal, Reaction, Friction, Air frication and
Weight)
