This content presents a solved physics problem that calculates the frictional force and acceleration of a 3.5 kg block pushed along a horizontal floor by a 15 N force at a 40° angle to the horizontal. It demonstrates the application of...

Newton's first law tells us that an object in motion will remain in motion, but we don't really see that on earth, do we? If you throw a ball, or push a hockey puck, these things do eventually stop. Why? To answer this we must learn...

A birthday party isn’t complete without cake, music and drama! This lesson will introduce the most common types of contact forces encountered in Physics.

Definitions included: contact force, normal force, friction force, static...

In this video, the sport of Hammer throw is explained and how physics plays a crucial role in achieving a long-distance throw. The concept of centripetal force and how it affects circular motion is discussed with the help of an...

Lotus isn’t the only one who has noticed that Ian is up to something… This lesson will explain how dynamic friction is dependent on the normal force and roughness of a surface, but independent of speed and apparent contact...

Kinetic friction summary

Vector Man rescues a waiter from a burning restaurant, but forgets to put out the fire! This lesson will explain how to draw free body diagrams.<br/>
Definitions included: free body diagram, net external force

Upon viewing the Things in Motion video series, students will be able to do the following: Identify a moving object and describe its movement as related to its frame of reference. Provide examples of forces in everyday life such as a...

In this video Paul Andersen describes the relationship between energy and forces. When objects are directly touching electromagnetic forces can result in forces and energy exchange. When objects are not directly touching fields;...

Lesson 14 (Rotation and Torque) of Dianna's Intro Physics Class on Physics Girl. Never taken physics before? Want to learn the basics of physics? Need an AP Physics 1 review before the exam? This course is for you! Exercises in this...

In this physics lesson, we break down how the force of friction always opposes sliding motion, whether it’s static or kinetic friction. Through clear demonstrations, motion tracking, and connections to Newton’s Laws of Motion, you’ll see...

Friction is the resistance that one object or surface experiences when moving over another object or surface. The two types of friction that come into play when moving two objects against one another are static and kinetic. Static...

What is friction? What are the two types of frictional forces?<br/>
Newton's Laws Of Motion With Friction, Part 1

New ReviewFriction always acts to oppose sliding motion, even when it makes an object speed up. Learn how this works with a clear and simple example using a sliding disk and a moving block.

This content explores the kinetic energy of a rolling object, comprising both rotational kinetic energy (1/2 I omega^2) and translational kinetic energy (1/2 M v_com^2). It emphasizes energy conservation in rolling, the crucial role of...

Dive into the physics of uniform and vertical circular motion and understand how centripetal force keeps objects moving in a circle. Explore real-life scenarios, derivations, and Class 11 exam-level insights with clarity

Real World Science: Force is one of a series of videos that encourages children to explore the world of science in their immediate surroundings. Through observation and experimentation, students will learn properties of forces, Newton's...

A moving object doesn’t always have a force in the same direction as its motion. Learn why with this simple hockey puck example and deepen your understanding of Newton’s laws.

This content solves a multi-part physics problem involving a solid ball that first rolls smoothly along a horizontal path, then up a ramp onto a plateau, and finally launches horizontally to land at a specific distance. It demonstrates...

Discover how Newton’s First Law, or the Law of Inertia, explains everyday motion—why objects stop, when they keep going, and how friction plays a role. Learn with relatable examples like sliding books, parked cars, and ice skaters.

This video explains the concept of friction, which is a force that exists between two objects that resists motion. The video discusses the two types of friction, static and kinetic, and explains how they work. It also explains how the...

Understand the four key types of forces—gravitational, normal, frictional, and tension—and how they affect motion. Learn to classify, analyze, and apply these forces to solve mechanics problems
