Lesson 1
This is the term referring to a point to or from which a person or thing moves or faces.
What is direction?
This relative object is used as a marker to determine if an object is technically "in motion".
What is a reference point?
This is the mathematical function is used to calculate speed and velocity.
What is division?
This term is when two objects come into contact with one another and is defined as a single event in which two bodies exert a force on one another.
What is a collision?
This is the base unit of acceleration.
What is meters per second per second (m/s2)?
DOUBLE
Newton's First Law of motion is based around this concept.
What is inertia?
Newton's First Law is, “An object at rest stays at rest and an object in motion remains in motion at constant speed in a straight line unless acted on by an unbalanced force”.
This object determines the direction(s) that will be positive when measuring motion.
What is the reference point?
This line on a graph shows that an object is changing its position at a constant rate over time.
What is a straight, slanting line?
Remember, in practicality you will have to differentiate between positive/negative direction when drawing your line; "does the line slant upwards or downwards".
This is added to ensure that a vehicle crash is inelastic and is crushed upon impact.
What are crumple zones?
These are exerted to attempt to put an object into motion.
What are unbalanced forces?
This is the base unit of force.
What are newtons?
Force is characterized by its direction and this.
What is its strength?
This is the base unit of velocity.
What is meters per second (m/s)?
Which of Newton's Laws explains that force is an interaction between two objects that exert force on one another?
What is the 3rd Law of Motion?
"For every action, there is an equal and opposite reaction. “I pull on the Earth and it pulls on me”
Friction force is exerted by an object interacting with another object with this action.
What is sliding?
Objects that do not naturally propel themselves have this stance on motion.
What is they do not want to move.
Remember, unbalanced forces are what put objects at rest into motion, and an object can still be in motion with a net force of 0 (balanced forces).
Galileo laid the framework for Isaac Newton with his motion experiment in this year.
What is the year 1604?
This is the velocity that can be calculated at any point during the duration of an object's motion.
What is the instantaneous velocity?
This type of collision is characterized by the total kinetic energy of the two bodies remaining the same on impact.
What is an elastic collision?
Remember, this will take place between objects with hard surfaces, such as a bowling ball striking pins or a pool ball striking another pool ball.
This acronym is the only unit of motion that is not represented by the metric system.
What is miles per hour (MPH)?
There are this many categories of force.
What are 2?
Do not get your categories confused with your types (applied, normal, gravitational, etc).
Distance forces affect objects within this futuristic vocabulary term.
What are force fields?
These are where distance force is felt. The farther into a force field an object goes, the more force that object will feel; think about your mass vs. the Earth and how it keeps your feet on the ground.
DOUBLE
This is the main difference between velocity and speed conceptually.
What is velocity uses direction?
This value for motion has a formula where you first subtract your final velocity from your initial velocity before diving by the amount of time that your object was in motion.
What is acceleration?
Remember your units!
DOUBLE
This scientist is credited with the assertion that opposites attract.
