MOTION & FORCE

Motion

The change in position of an object in respect to time & reference point

Static

It deals with objects at rest

Dynamics

It deals with moving objects

Kinetic

Explaine the force behind the motion

Kinematic

Explains how the objects moves

Translational, Rotational, Oscillatory, Periodic

4 Types of motion

Scalar

It only involves motion with magnitude (no. & unit)

Vector

Involves magnitude and direction (6 km/h West)

Translational Motion

The motion of an object that moves in a straight line or curved path.

All parts are moving in the same direction and motion

Rotational Motion

The object turns in a fixed point or axis

Oscillatory Motion

A back & forth motion at an equilibrium point (also a periodic motion)

Periodic

Motion that repeats after a fixed amount of time

Contact Force & Non-Contact Force

2 Types of Force

Contact Force

Requires contact or physical contact between the objects

Non-Contact Force

A type of force that does not require contact

Friction, Applied, Normal, Tension

4 types of Contact Forces

Applied

What type of CONTACT FORCE is the action of pushing a cart?

Normal

What type of CONTACT FORCE is it when an object id prevented from passing one another?

Tension

What type of CONTACT FORCE it is when you pull a rope?

Strong Nuclear, Weak Nuclear, Electromagnetic, Gravitational

4 Types of Non-Contact Forces

Strong Nuclear

Non-contact force that holds the protons & neutrons

Weak Nuclear

Non-contact force that is responsible for radioactive decay and nuclear fusion

Electromagnetic

Non-contact force that involves electric-charged particles and is responsible for maintaining the structure of an atom

Gravitational

Non-contact force that is responsible in maintaining Earth's gravity
