Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

After completing this Lecture Tutorial, students should be able to:
distinguish between scientific hypotheses and nonscientific ideas.
Part 1: Comprehension of Hypotheses
A scientific hypothesis needs to (1) be supported by the majority of current data and (2) be
testable. An alien on Earth is wondering why a rubber ball falls back down to the ground
after it is thrown into the air. It comes up with several ideas about the ball.
a. Gravity is pulling the ball to the ground.
b.
A mystical force that cannot be measured is pushing the ball down.
c.
Earth's magnetic field is pulling on the rubber ball.
1. Which statement is NOT a hypothesis because it is not testable? a b c
2. Which statement is NOT a hypothesis because it is not supported by current data? a b c
3. Which statement IS a scientific hypothesis? a b c
Part 2: Application to Dinosaur Extinction
Below are possible scenarios explaining the extinction of the dinosaurs.
a. Dinosaurs were killed off by a virus.
b. A large meteorite impact caused the climate to change, so some plants and animals
could no longer survive.
c. Volcanic eruptions caused the climate to change, so some plants and animals could no
longer survive.
d. Mammals ate all the dinosaur eggs.
4. Determine if each statement above is a valid hypothesis. Explain your answer using the
requirements of a scientific hypothesis.
a.
Yes
No
