3. Linear Motion: Terms & Definitions Flashcards
Angular Motion
A change in orientation, rotation around a fixed axis
Axis of Rotation
The axis of rotation is an imaginary line around which an object rotates, with all points on the object moving in circular paths centered on this line
Curvilinear Motion
Curvilinear motion is the movement of an object along a curved path, where the direction of motion continuously changes but the object follows a smooth trajectory.
Displacement
Change in Position from starting point to ending point
Vector
Distance
Total amount travelled
Scalar
Dynamic State
Dynamic state refers to a condition in which an object is in motion, experiencing changes in velocity or direction due to unbalanced forces.
General Motion
Combined linear and angular motion
Linear Kinematics
Linear Kinematics
Linear Motion
Linear motion is the movement of an object along a straight line, where all parts of the object move in the same direction and cover the same distance.
Motion
Motion is the change in position of an object over time relative to a reference point.
Pace
Pace is the rate or speed at which an activity, such as walking or running, is performed, typically measured in time per unit of distance.
Rectilinear Motion
Rectilinear motion is the movement of an object along a straight line, where the direction and path remain consistent throughout the motion.
Rotation
Rotation is the circular movement of an object around a central point or axis, where all parts of the object follow a circular path.
Scalar
A scalar is a quantity that has only magnitude and no direction, such as mass, temperature, or time.
Speed
Speed is the rate at which an object covers distance, defined as the total distance traveled divided by the time taken, without considering direction.
Static State
Static state refers to a condition in which an object remains at rest, with no movement or changes in velocity, due to balanced forces acting on it.
Translation
Translation is the movement of an object in which all parts move in the same direction and distance, without any rotation or deformation.
Vector
A vector is a quantity that has both magnitude and direction, commonly used to represent physical concepts like force, velocity, or displacement.
Velocity
Velocity is the rate of change of an object’s displacement in a specific direction, making it a vector quantity that includes both speed and direction.
