The video tutorial explains the relationship between momentum change and resultant force using Newton's second law. It demonstrates how to calculate force, velocity, and time through examples involving a car, a lorry, and a cyclist. The tutorial emphasizes the application of the formula F = m * a and the concept of momentum as mass times velocity, providing step-by-step calculations to solve physics problems.

What does Newton's second law relate to in terms of an object's motion?

• The change in mass of an object

• The change in momentum of an object

• The change in temperature of an object

• The change in color of an object

In the context of Newton's second law, what does the symbol 'F' represent?

• Force

• Friction

• Frequency

• Flux

How is momentum defined in terms of mass and velocity?

• Momentum is the sum of mass and velocity

• Momentum is the difference between mass and velocity

• Momentum is the product of mass and velocity

• Momentum is the ratio of mass to velocity

What is the unit of momentum?

What is the final velocity of the lorry after a force of 2000 newtons acts on it for 2 seconds?

• 1.6 meters per second

• 2.0 meters per second

• 3.0 meters per second
