Kinematics 1
The study of motion using words, numbers, graphs, and equations.
What is Kinesthetics?
What is displacement?
Diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation.
What are free body diagrams?
The study of forces and their effect on motion.
What is Dynamics?
The weakest of the fundamental forces. An attractive force that works over long distances and is universal.
What is Gravitational Force or Weight?
A quantity with both magnitude and direction
What is a Vector?
The rate at which an object changes its position. A vector quantity that includes both magnitude and direction.
What is velocity?
Support force, perpendicular to the surface.
What is normal force?
opposes motion parallel to the surface.
What is friction force?
The numerical measure of inertia.
What is mass?
An object thrown into the air and only acted on by gravity.
What is projectile?
A number with a unit (magnitude only)
What is Scalar?
Force through a string, rope, cable, or wire when pulled tight.
What is tension force?
A force that causes a change in motion.
What is an unbalanced force?
Forces that result when the two interacting objects are not physical in contact, yet are able to exert a push or pull.
The velocity of an object in motion at a specific point in time.
What is instantaneous velocity?
Size or dimensions, quantity.
What is magnitude?
For every action, there is an equal and opposite reaction.
What is Newton's 3rd Law?
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Two objects attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them.
What is the universal law of gravitation?
A vector that represents the sum of two or more other vectors.
What is a resultant?
Any coordinate system that is either at rest or moving in some direction with a constant velocity.
What is Inertial Reference Frame?
A portion of the physical universe chosen for analysis.
What is a system?
The resistance an object has to a change in its state of motion.
What is inertia?
Relates the magnitude of the gravitational attractive force between two bodies and their masses and the distances between them.
What is gravitational constant?
