FAQs on Force - 1 Video Lecture - Physics Class 6 ICSE

1. What is force in science?
Ans. Force is a push or pull that can change the motion of an object. It is measured in newtons (N) and can cause an object to start moving, stop moving, or change direction.
2. What are the different types of forces?
Ans. There are various types of forces, including gravitational force, frictional force, magnetic force, and applied force. Each type has its own characteristics and effects on objects.
3. How does mass affect the force applied to an object?
Ans. The mass of an object affects the force needed to move it. According to Newton's second law of motion, force equals mass times acceleration (F = m × a). Therefore, a heavier object requires more force to accelerate than a lighter one.
4. What is the difference between balanced and unbalanced forces?
Ans. Balanced forces are equal in size and opposite in direction, causing no change in an object's motion. Unbalanced forces occur when one force is greater than another, resulting in a change in motion, such as acceleration.
5. How can we calculate force using Newton's second law?
Ans. To calculate force using Newton's second law, you can use the formula F = m × a, where F is the force in newtons, m is the mass of the object in kilograms, and a is the acceleration in meters per second squared. This formula helps determine how much force is needed to move an object.
