Discover the impact of a 0.09-N thrust engine on a 480 kg spacecraft's speed during 1 week of maximum power operation. Uncover the assumptions involved in this space physics scenario.

Learn how to determine the hot resistance and current in the electrical system of older cars with a 6.00-V voltage supply.

In this video we tackle the real-world physics problem of calculating the spring constant for a fisherman's scale along with the amplitude and frequency of its vibrations when a fish is added. We use Hooke's Law to find the spring constant and then apply oscillation formulas to determine the amplitude and frequency of the fish's vibrations

Step into the showroom as we explore the intriguing connection between rug dimensions and area. Learn whether a rug being twice as long as another implies its area is also doubled. Join us for a comprehensive explanation of this geometric concept.

Delve into Newton's third law of motion and explore how the choice of the 'system of interest' influences whether force pairs cancel each other out.

Explore how a mass spectrometer works by analyzing an ion's path through the device. Understand the relationship between electric and magnetic fields in determining the ion's trajectory. Learn to compute the radius of an ion's path within the mass spectrometer.
