FAQs on Momentum Video Lecture - Physics for GCSE/IGCSE - Year 11

1. What is momentum in physics?
Ans. Momentum in physics is a property of a moving object that is related to its mass and velocity. It is the product of an object's mass and its velocity.
2. How is momentum calculated?
Ans. Momentum is calculated by multiplying an object's mass by its velocity. The formula for momentum is: Momentum = mass x velocity.
3. What is the difference between momentum and inertia?
Ans. Momentum is a measure of how difficult it is to stop a moving object, while inertia is an object's resistance to changes in its state of motion. Momentum depends on both the mass and velocity of an object, while inertia only depends on the mass.
4. Why is momentum important in collisions?
Ans. Momentum is important in collisions because it is conserved. This means that the total momentum before a collision is equal to the total momentum after the collision, regardless of the type of collision. By using the principle of conservation of momentum, we can analyze and predict the outcomes of collisions.
5. How does momentum affect the motion of objects?
Ans. Momentum affects the motion of objects by influencing their speed and direction. Objects with larger momentum are harder to stop or change their direction compared to objects with smaller momentum. In this way, momentum plays a crucial role in determining how objects move and interact with each other.
