Motion

is a change in position of an object over time.

TRANSLATIONAL MOTION

Occurs when all parts of an object move the same distance in the same direction.

Displacement

m

Velocity

m/s

Acceleration

m/s²

Rotational Motion

Occurs when an object spins or rotates around a fixed axis.

Angular displacement

radians or degrees

Angular velocity

rad/s

Angular acceleration

rad/s²

v=rw

ERGONOMIC DESIGN

These designs are guided by principles of force distribution, torque balance, and motion mechanics to minimize strain on muscles and joints

lever and gear mechanisms

Adjustable chairs, desks, and monitor stands use __to change height and orientation with ease.

TECHNOLOGY AND ELECTRONICS

The cooling fans inside computers apply thermodynamics to manage heat transfer, preventing components from overheating

Electromagnetic waves

enable data transfer across networks and wireless systems, allowing fast communication

electrical energy into light energy

Meanwhile, LED and LCD displays convert __, illustrating the conversion of energy forms—a fundamental physics concept.

SPORTS AND MOTION

Every kick, throw, jump, or swing demonstrates the fundamental laws of motion.

projectile motion

For instance, the curved path of a basketball shot illustrates ___, where the force of gravity continuously pulls the ball downward while it moves forward in an arc.

gravitational potential

The car is pulled up a steep hill, building

gravitational potential energy, kinetic energy

The car is pulled up a steep hill, building . As it descends, that stored energy converts into ___, propelling the car forward at high speed, all due to the interplay of acceleration, gravity, and inertia.

optics and light polarization

In 3D movies, each lens of the special glasses filters light waves differently, allowing each eye to see a slightly different image. The brain then merges these two perspectives, creating a sense of depth perception. This process, based on ___, mimics how human vision works naturally.

physics of sound waves

Sound systems in theaters, concerts, and headphones operate using the

light refraction,  motion sensors and gyroscopes

VR headsets use ___ through lenses, along with_________, to detect every movement of the user’s head. As you turn or tilt your head, the display adjusts accordingly creating an illusion of being inside a 3D environment. This integration of optics, motion, and energy transfer allows VR users to explore virtual worlds as naturally as they would in real life.
