PHYSICS
Studies heat, temperature, energy, and their transformations.
Thermodynamics
Types of Linear motion
Rectilinear and Curvilinear
It is a basic tool that makes work easier by helping you move, lift, or cut things with less effort.
Simple machine
formula for speed
speed=distance/time
What is the SI unit of angular displacement?
Radians
Studies electric and magnetic fields and their interactions.
Electromagnetism
It is defined as the length of the actual path travelled by a particle in motion.
Distance
is a flat surface that is tilted, like a ramp. It helps you move objects up or down more easily by using less force.
Inclined plane
formula for distance
d=s(avg.)/time
the angle measured in radians and is defined as the shortest angle between the initial and the final points for a given object undergoing circular motion about a fixed point.
Angular Displacement
Branch of Physics that deals with the motion of objects and the forces acting upon them, especially at the macroscopic scale and low speeds
Classical Physics/Mechanics
It is defined as the rate of change of angular velocity with respect to time.
Angular acceleration
Is a simple machine that looks like a twisted inclined plane wrapped around a rod.
Screw
What is displacement?
The change in position of an object.It is a vector quantity and has a direction and magnitude
The amount of rotation about the point of intersection of two planes (or lines) which is required to bring one in correspondence with the other.
Angle
What is Physics?
branch of science that helps us understand how things move, how energy works, and what rules or forces control everything in the universe.
What is translational motion?
when an object moves from one place to another in a straight line or along a curved path, and every part of the object moves the same distance in the same direction.
It is a tool made by combining two or more simple machines.
compound machine
The distance traveled along the curved path between the initial and final positions.
Arch Length
The distance from the center of the circle to the moving object.
Radius
The concepts and theories developed in the 20th century and beyond, including quantum physics and relativity
Modern Physics
What is Rotational motion?
when an object spins or rotates around a fixed point or axis. In this motion, different parts of the object move in circles, but the whole object doesn’t move from place to place.
What is a function of a Pulley?
It helps you lift or move heavy objects more easily by changing the direction of the force you use.
A car increases its speed from 10 m/s to 30 m/s in 5 seconds. What is the acceleration of the car?
4 m/s2
Calculate: A boy runs 40 meters east in 8 seconds. What is his velocity?
5 m/s East
