FAQs on Motion -General Science, Exam Preparation

Question 1

1. What is motion in general science?

Accepted Answer

Ans. In general science, motion refers to the change in position of an object over time with respect to its surroundings. It can be described in terms of distance, displacement, speed, velocity, and acceleration.

Question 2

2. What are the different types of motion?

Accepted Answer

Ans. There are several types of motion, including linear motion (motion along a straight line), circular motion (motion along a circular path), rotational motion (spinning or turning motion), oscillatory motion (back and forth motion), and projectile motion (motion of an object thrown into the air).

Question 3

3. How is speed different from velocity?

Accepted Answer

Ans. Speed and velocity are related but different concepts. Speed is the distance traveled per unit of time, whereas velocity is the displacement (change in position) per unit of time, including the direction. Velocity takes into account both the magnitude and direction of motion.

Question 4

4. What is acceleration and how is it calculated?

Accepted Answer

Ans. Acceleration is the rate at which an object changes its velocity. It can be calculated using the formula: acceleration = (final velocity - initial velocity) / time taken. Acceleration can be positive (speeding up), negative (slowing down), or zero (constant velocity).

Question 5

5. How does Newton's first law of motion relate to the concept of inertia?

Accepted Answer

Ans. Newton's first law of motion states that an object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force. This concept is related to inertia, which is the tendency of an object to resist changes in its motion. Inertia is directly proportional to the mass of an object.
