Free-falling Bodies: Example01:05

Free-falling Bodies: Example

An object falling without any air resistance under the influence of gravitational force is said to be in free-fall. For free-falling bodies, the acceleration due to gravity is constant, irrespective of their mass. Free-fall is experienced not only by objects falling downward, but also by all objects whose motion is influenced by gravitational force alone. The dynamics of free-fall motion can be calculated using kinematic equations of motion, since free-fall acceleration is constant.

Free-falling Bodies: Introduction01:07

Free-falling Bodies: Introduction

All objects, neglecting air resistance, fall with the same acceleration towards the Earth's center due to the force exerted by the Earth's gravity. This experimentally determined fact is unexpected because we are so accustomed to the effects of air resistance and friction that we expect light objects to fall slower than heavier ones. People believed that a heavier object had a greater acceleration when falling until Galileo Galilei (1564–1642) proved otherwise. We now know this is...

Dealing With Competition - Assess the Competitors

Competitor evaluation is essential for refining business strategies, and a SWOT analysis is an effective tool. It examines strengths, weaknesses, opportunities, and threats. For example, a retail company might recognize a competitor's strength in supply chain efficiency but identify a weakness in customer service. This detailed insight allows businesses to better position themselves in the market by addressing gaps that competitors may have overlooked.

Dealing With Competition - Identify the Competitors

Competitor identification is crucial for effective strategic planning. Using frameworks like Porter’s Five Forces, industry analysis helps evaluate competitive factors such as the intensity of rivalry and the threat of new entrants. In the smartphone industry, for example, manufacturers closely monitor the presence of emerging brands, assessing how their entry may disrupt pricing and innovation. Additionally, benchmarking key performance indicators (KPIs) such as revenue growth and...
