Position vs. Time Graph - Part 1
Mr. Andersen shows you how to interpret a position vs. time graph for an object with constant velocity. The slope of the line is used to find the velocity. A phet simulation is also included.

Motion in a Straight Line: Crash Course Physics
In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity, and the definition of acceleration. Also,...

Spacetime
In this video Paul Andersen explains how the dimensions of space and time are combined in relativistic mechanics. Gravity and velocity can affect both space and time according to Albert Einstein's Special Law of Relativity.

Terminal Velocity
The terminal velocity of an object is the speed at which the force of drag equals the force of gravity on that object.

Center of Mass
In this video Paul Andersen explains how the center of mass of an object represents the average position of matter in an object. The center of mass of a system is a combination of all the objects within the system. As long as no external...

How Do You Weigh Things in Space?
Astronauts need to know their mass while in orbit, but a normal scale would be free-falling around the Earth with them. So how do they measure their mass without gravity?

Integrals: Crash Course Physics
Continuing with last week's introduction of calculus, Shini leads us through the ways that integrals can help us figure out things like distance when we have several other key bits of information. Say, for instance, you wanted to know...

Motion
In this video Paul Andersen describes motion as the movement of an object over time. Displacement, velocity and acceleration are all defined. An experiment in motion is used to calculate velocity and acceleration of a tennis ball.

Rotational Motion
In this video Paul Andersen explains how a net torque acting on an object will create rotational motion. This motion can be described by the angular displacement, angular velocity, and angular acceleration. The linear velocity can be...

Uniform Circular Motion: Crash Course Physics
Did you know that centrifugal force isn't really a thing? I mean, it's a thing, it's just not real. In fact, physicists call it a "Fictitious Force." Mind blown yet? To explore this idea further, this week Shini sits down with us to...

Position, Velocity and Acceleration
In this video Paul Andersen explains for the position of an object over time can be used to calculate the velocity and acceleration of the object. If a net force acts on a object it will experience an acceleration.

Scalars and Vectors
Mr. Andersen explains the differences between scalar and vectors quantities. He also uses a demonstration to show the importance of vectors and vector addition.

Angular Impulse
In this video Paul Andersen explains how the change in angular momentum is equal to the torque applied over a given time. A sample problem and inquiry activity are included.
Bozeman Science
Forces
Forces are pushes or pulls on an object. Forces can be determined by measuring the motion of an object. If an object accelerates then a force is present.

Rotational Motion: Crash Course Physics
Did you know that, at a certain point on a moving wheel... there's no motion? I mean, kinda... it's all relative, right? Prepare to have your mind blown in this episode of Crash Course Physics where Shini delves into the world of...

What is Physics?
Mr. Andersen explains the importance of physics as a science. History and virtual examples are used to give the discipline context.

Newton's Three Laws of Motion
Mr. Andersen defines Newton's three laws of motion. He describes how the first law relates to inertia, how the second law relates to mass and acceleration, and how the third law allows a rocket to launch.

Newtons 2nd Law of Motion | Force, Mass, Acceleration
Newton's 2nd Law of Motion tells us that if a net force is applied to an object then that object will accelerate in the direction of the net force. This means that is a force a force is applied to an object, it will either speed up, slow...

Graphing Acceleration Explained - Velocity versus Time!
A velocity vs time graph describes the motion of an object. The slope of the line tells us the acceleration of the object. The slope of the line can be positive, negative or zero. This tells us that the object is either speeding up,...

The ONE thing your teacher is NOT telling you that will simply forces!
Forces are all around us and are the reason why objects accelerate (speed up, slow down or change direction)! Forces can either be balanced or unbalanced. When the forces are balanced, the net force is 0 and the object's motion will not...

Simplifying Acceleration Calculations
Acceleration is the rate of change in velocity over time. Acceleration can be calculated using the formula a=vf-vi/t. Acceleration can be positive, which means speeding up, negative which means slowing down and it can also be 0 which...

How to Calculate Force - Newton's 2nd Law of Motion
Newton's 2nd Law tells explains how force can affect the acceleration of an object. The more force you apply to an object, the more it will accelerate. Also, the more mass an object has, the more force that is needed to cause the object...
