Billy does an example problem to review the work equation.

This video is a lecture on the topics of gravity and orbits. The speaker starts by discussing how objects in orbit remain in orbit due to the gravitational force experienced from other celestial bodies. They then explain how the...

Learn how to use the Conservation of Mechanical Energy equation by solving a trebuchet problem.

Review of all of the Kinematics topics covered in the AP Physics 1 curriculum. Plus some bonus introductory stuff.

The video explains how waves can be categorized according to two sets of criteria: transverse or longitudinal, and mechanical or electromagnetic. It gives examples of waves that fit each category, such as water waves as a transverse...

A 453 g toy car moving at 1.05 m/s is going over a semi-circular hill with a radius of 1.8 m. When the car is at the top of the hill, what is the magnitude of the force from the ground on the car?

Review of the Electricity topics covered in the AP Physics 1 curriculum.

A basic rotational form of Newton’s Second Law problem with only one force.

👉 Learn how to apply transformations of a figure and on a plane. We will do this by sliding the figure based on the transformation vector or directions of translations. When performing a translation we are sliding a given figure up,...

In 1884, engineer Nikola Tesla was hired by Thomas Edison’s Headquarters in New York City. Tesla idolized Edison, but the two had one fundamental disagreement; Edison favored DC, Direct Current, in which electricity flows in one...

In this lesson, students will learn how to find the exact Radian measure of angles without using a calculator. They will recognize special angles as fractions or multiples of π and understand that π radians is only half of a circle. By...

The wave-particle duality seems to used all the time to explain quantum mechanics to the public, but it is one of my pet peeves. It represents an outmoded way of thinking (old quantum theory), which is replaced by our current...

The grandfather paradox is considered the biggest, most popular objection to the logical possibility of backwards time travel. It characterizes a hypothetical situation in which a time traveller goes to their past and ends up causing an...

When you hear the roar of traffic, the bark of a dog, or your teacher's voice, you are experiencing sound. This program uses colorful animations to explore important characteristics of sound, including intensity, loudness, pitch, and...

A 0.453 kg toy car moving at 1.15 m/s is going up a semi-circular hill with a radius of 0.89 m. When the hill makes an angle of 32° with the horizontal, what is the magnitude of the force normal on the car?

In the workplace it can be challenging to hold your ethical position when others may not share the same views. It is important to understand that peer pressure can make it hard or intimidating to stand up for your ethical principles but...

In this video, students learn about opposite numbers on a number line and how they can be combined to make zero. Using real-life examples involving distance and direction, the video demonstrates how positive and negative directions can...

A rainy day spent inside helps a little boy learn about clouds and the water cycle from his mother. He sees the value of rain to plants, animals, people and the planet, even when the rain is not convenient for him. As the rain...

Solving a basic projectile motion problem using unit vectors.

Description and examples of g-forces or number of g’s.

This video explains the basics of one-dimensional motion, including distance, displacement, speed, and velocity. It also introduces the concept of acceleration and provides equations to calculate these values. These concepts are...

Mr. Clifford's explanation of the Law of Demand and the Law of Supply. He also shows why demand curves are downward sloping and supply curves are upward sloping. Please keep in mind that these clips are not designed to teach you the...

Students will explore the principles of motion, the basic concepts of speed and velocity and how speed and acceleration are calculated. Numerous examples of common occurrences illustrate the principles of motion. Other terminology...

In this video, the teacher explains how to determine the length of the radius of a circle from its diameter. The concept of a circle is explored, emphasizing that the radius is half the length of the diameter. Examples are given to...
