An object falling from a short distance (e.g. 5cm) has less of an impact than the same object falling from a height of 5m.
But why is it traveling faster?rootone said:The object which is dropped from a greater height will be traveling faster when it hits the ground.
Have you studied rectilinear motion?motleycat said:But why is it traveling faster?
It takes longer to fall from a greater height because there's more distance to cover before the falling object hits the ground. That gives gravity more time to accelerate the falling object.motleycat said:But why is it traveling faster?
motleycat said:No, I am in a physics course for social science students. They keep it very simple.
If the object falls for t seconds, the velocity will be gt when it hits the ground, with g = 9.807 m/s^2, but the vertical distance covered is (1/2)gt^2. (the falling time multiplied by the average velocity).ScooterGuy said:So, for instance, a penny dropped from 9.807 meters with a starting velocity of 0 m/s will fall for exactly one second and will be traveling at 9.807 m/s (21.9 MPH) when it hits the ground. A penny dropped from 19.613 meters with a starting velocity of 0 m/s will fall for exactly two seconds, and will be traveling at 19.613 m/s (43.8 MPH) when it hits the ground. A penny dropped from 29.419 meters with a starting velocity of 0 m/s will fall for exactly three seconds and will be traveling 29.419 m/s (65.8 MPH) when it hits the ground.
As a scientist, it is important to be able to communicate complex concepts in a way that is easy for everyone to understand. To explain something in simple terms, I would break down the concept into smaller parts and use everyday examples or analogies to make it relatable.
Visual aids such as diagrams, charts, and graphs can be very helpful in explaining scientific concepts. I would use these tools to illustrate the concept and make it easier to understand and remember.
Understanding the importance of a concept is crucial in the scientific field. I would explain how this concept contributes to our understanding of a larger topic or how it can be applied in practical situations.
Using real-life examples can make a concept more relatable and easier to understand. I would provide examples from nature or everyday life to show how this concept is present and relevant in our world.
In science, many concepts are interconnected and build upon each other. I would explain how this concept is related to other known theories or principles, and how it fits into the larger scientific picture.
