Studied by 5 people
Displacement
a vector quantity that describes a change in position.
Distance
how far an object moves during a time interval.
Scalar
a measurable quantity that consists of magnitude (size) only.
Kinematics
the study of how things move.
Dynamics
the branch of physics that studies forces and how they can change an objects motion.
Vector
a measurable quantity with both magnitude and direction.
Acceleration
the rate of change in velocity.
Trajectory
the curved path of a projectile.
Velocity
a vector quantity indicating the rate at which an objects position changes.
Free fall
the motion of an object that falls due to gravity alone, with no other forces acting on it.
Momentum
a property of a moving system that is equal to its velocity times its mass.
Quantum mechanics
the branch of physics that explores the behavior of matter and energy at the atomic and subatomic level.
Frame of reference
a coordinate system used to describe the motion of an object.
Relativistic mechanics
the study of the motion of objects whose speeds are near the speed of light.
Projectile motion
the two- dimensional motion of any flying object whose path is determined by the influence of an external force only, such as gravity.
mechanics
the study of motion
kinematics
the study of how things move
dynamics
the branch of physics that studies forces and how they can change an objects motion
retrograde motion
the apparent motion of some planets in which they appear to slow down, stop, reverse their direction, and then resume their normal motion
