8 Definitions to memorise (8 cards)
What is the normal force?
The force or component of a force which a surface exerts on an object with which it is in contact, and which is perpendicular to the surface.
What is the frictional force?
The force that opposes the motion of an object and which acts parallel to the surface.
What is static frictional force?
The force that opposes the tendency of motion of a stationary object relative to a surface.
What is kinetic frictional force?
The force that opposes the motion of a moving object relative to the surface.
What is Newton’s 1st Law?
A body will remain in its state of rest or motion at constant velocity unless a non-zero resultant/net force acts on it.
What is Newton’s 2nd Law?
When a net force acts on an object, the object will accelerate in the direction of the force and the acceleration is directly proportional to the force and inversely proportional to the mass of the object.
What is Newton’s 3rd Law?
When object A exerts a force on object B, Object B simultaneously exerts an oppositely directed force of equal magnitude on object A.
What is Newton’s Law of Universal Gravitation?
Each body in the universe attracts every other body with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
