FAQs on NCERT Solutions for Class 7 Science Chapter 13 Motion And Time

What is the use of motion and time?

Motion and time help us understand how objects move and change position over time. They are essential concepts in physics to describe the movement of things around us.

What I learn from the chapter motion and time?

From the chapter on motion and time, you learn about different types of motion, how to measure speed, calculate distances, interpret distance-time graphs, and understand the relationship between time and motion.

How many types of motion are there?

There are three main types of motion: straight line motion, circular motion, and oscillatory motion. Each type of motion involves objects moving in different paths or patterns.

Does time depend on motion?

Time is independent of motion; it is a constant measure that helps us track events and changes. However, motion can affect how we perceive time, especially in relation to speed and distance covered.

What causes motion?

Motion is caused by forces acting on objects. When a force is applied to an object, it can cause the object to move. Forces like gravity, friction, and applied forces can all lead to motion.

What is uniform motion?

Uniform motion is when an object travels in a straight line at a constant speed. In uniform motion, the object covers equal distances in equal intervals of time, maintaining a steady pace.
