Studied by 1 person
The total length of the path traveled by an object, regardless of its direction.
Distance
The shortest distance from the initial to the final position of an object, including direction. Displacement is a vector quantity.
Displacement
The rate of change of displacement of an object with respect to time. It is a vector quantity that includes both speed and direction.
Velocity
The total displacement of an object divided by the total time taken for that displacement. also a vector quantity.
Average velocity
The rate at which an object covers distance, regardless of direction. It is a scalar quantity.
Speed
The total distance traveled by an object divided by the total time taken for that distance. Unlike average velocity, it does not take direction into account.
Average speed
The motion of an object that is thrown or projected into the air, subject to the force of gravity, which follows a curved trajectory called a parabola.
projectile motion
the path traveled by projectile also called parabolic path
trajectory
the motion of an object traveling at a constant speed in a circular path, where the direction of the velocity changes continuously.
uniform circular motion
the acceleration of an object moving in a circular path directed towards the center of the circle.
centripetal motion
the branch of physics dealing with the motion of objects and the forces acting on them.
mechanics
the study of forces and their effects on motion.
dynamics
the study of forces in the absence of motion, focusing on equilibrium.
static
two branch of dynamics
kinematics and kinetics
the branch of mechanics that deals with the motion of objects without considering the forces that cause the motion.
kinematics
the branch of mechanics that deals with the forces acting on objects and the motion that results from those forces.
kinetics
push or pull acting in an object that causes action
force
SI unit for force
Newton or kg m/s’2
the change in the position of a body with respect to time
motion
