To illustrate effective assessment answering, here are sample questions with detailed solutions.
Question 1:
Explain Newton’s First Law of Motion and give an example.
Answer:
Newton’s First Law of Motion states that an object at rest remains at rest, and an object in motion continues in motion at a constant velocity unless acted upon by an external force. This law is also known as the law of inertia.
Example: A book resting on a table remains stationary until someone pushes it. Similarly, a rolling ball on a smooth surface will keep rolling unless friction or another force slows it down.
Question 2:
A car accelerates from 0 to 20 m/s in 5 seconds. Calculate its acceleration.
Solution:
Using the formula:
a = (final velocity - initial velocity) / time
a = (20 m/s - 0 m/s) / 5 s = 20 / 5 = 4 m/s²
Answer: The car’s acceleration is 4 meters per second squared.
