Dynamic Basics
This is the SI unit composition of a Newton.
What is a kgdotm/s^2 ?
This is the study of forces and their effect on the motion of objects or systems.
What is Dynamics?
This attractive field force exists between any two objects with mass.
What is the gravitational force?
These are the laws related to force, acceleration, and intertia.
What are Newton's Laws?
This is the force required to accelerate 5kg at 2m/s2?
What is 10N?
Forces are said to be this when the sum of the forces acting on an object is zero.
What is balanced?
This is the definition of force.
What is a push or a pull on a system?
This contact force opposes motion.
What is friction?
This is Newton's second law written in math.
What is sumF=ma ?
This is the weight, in Newtons, of an 8th grade student with a mass of 50kg.
What is 500N?
Forces are said to be this when the sum of the forces acting on an object is NOT zero.
What is unbalanced?
This is a sketch of the vector forces acting on an object or system.
What is a Free Body Diagram?
This contact force reacts to compression and acts perpendicular to the contact surface.
What is the normal force?
This is Newton's 1st Law written in English.
What is "an object at rest tends to stay are rest and and object in motion tends to stay in motion unless acted on by an outside force"?
This is the acceleration of a 20kg rock being pushed with a force of 60N.
What is 3m/s2?
The weight of an object can be calculated using this equation.
What is Fg = mg?
These are forces that require objects or systems to be touching one another.
What are contact forces?
This contact force twists an object.
What is tortion?
This Newton's Third Law written in English.
What is "for every action there is an equal and opposite reaction"?
This is the mass of an object that is accelerated at 5m/s2 when a force of 2kN is applied.
What is 400kg?
These are the four fundamental forces in decreasing order of strength.
What are the strong nuclear, gravitational, electromagnetic, and weak nuclear forces?
These are forces that act at a distance and do not require contact.
What are field forces?
This contact force squeezes an object.
What is compression?
This is Newton's Second Law written in English.
What is "the acceleration of an object is directly proportional to the force applied and inversely proportional to the mass"?
This is the magnitude of the friction force when a 10kg object accelerates at 5m/s2 when a pushing force of 100N is applied.
