Question

lesson model: position, displacement, time, velocity
kinematics
how objects move
position, velocity, acceleration
dynamics
why objects move
force, energy, mass, momentum
kinematics describes ______ objects move
dynamics describes ______ objects move
position
position: where an object is at a single point in time
position: ______ an object is at a single point in time
in physics, position is often represented by the variable ______
the scientific standard (si) unit for position is the ______

Explanation:

Kinematics focuses on motion characteristics like position, velocity, acceleration to describe how objects move. Dynamics uses concepts like force, energy to explain why objects move. Position indicates where an object is at a moment. In physics, $x$ is a common variable for position, and the SI unit for position is the meter.

Answer:

• Kinematics describes: HOW
• Dynamics describes: WHY
• Position: WHERE
• In physics, position is often represented by the variable: $x$ (or other position - related variables like $y$, $z$ in multi - dimensional cases)
• The scientific standard (SI) unit for position is the: meter
