Vocab.
The rate at which velocity changes with time.
What is acceleration?
States the acceleration of an object is directly proportional to the net force and inversely proportional to the mass of an object.
What is Newton's Second Law of Motion?
Forces that act between two objects that are physically touching each other.
What is a contact force?
distance / time
What is the formula for speed?
Describes the location of an object.
What is position?
A quantity that has both size and direction.
What is vector?
States that every time an object exerts force on another object, the second object exerts a force that is equal in size and opposite in direction back on first object.
What is Newton's Third Law of Motion?
The force of attraction between two masses.
What is gravity?
distance / speed
What is the formula for time?
Represents the distance travelled in a straight line.
What is a distance-time graph?
Any force that keeps an object moving in a circle.
What is a centripetal force?
States that objects at rest stay at rest and objects in motion tend to stay in motion unless and unbalanced force is acted on it.
What is Newton's First Law of Motion?
A force that resists motion between two surfaces that are pressed together.
What is friction?
force / mass
What is the formula for acceleration?
Can be calculated from velocity and time.
What is acceleration?
The measure of how fast something moves or the distance it moves, in a given amount of time.
What is speed?
Relates force, mass, acceleration.
What is Newton's Second Law of Motion?
Have the same effect ad no force at all.
What are balanced forces?
mass x acceleration
What is the formula for force?
These are sometimes confused with action and reaction forces.
What are balanced force?
A location at which you can pair other locations.
What is a reference point?
What is Newton's First Law of Motion?
Can change the motion of an object.
What are unbalanced forces?
force / acceleration
What is the formula for mass?
States that the total momentum of a system of objects does not change, as long as no outside forces are acting on the system.
What is the Principle of Conservation of Momentum?
