Inertia: Understanding and Calculating Inertial Mass

The video tutorial explains inertia and how to calculate it using Newton's second law. It begins with an introduction to inertia and the concept of force needed to accelerate objects. Examples are provided using a car and a lorry to demonstrate force calculations. The tutorial then explains inertial mass and provides example calculations for a plane and a proton. The lecture concludes with a summary of the key points discussed.

What is the force required to accelerate a 900 kg car at 3.5 m/s²?

• 3200 Newtons

• 3150 Newtons

• 3500 Newtons

• 3000 Newtons

According to Newton's Second Law, what is the relationship between force, mass, and acceleration?

• F = M + A

• F = M / A

• F = A / M

• F = M * A

What does the inertial mass of an object measure?

• The speed of the object

• The difficulty in changing the object's velocity

• The volume of the object

• The weight of the object

How is the inertial mass of a plane calculated if the force is 6000 N and acceleration is 5 m/s²?

• 1200 kg

• 1300 kg

• 1500 kg

• 1000 kg

What is the inertial mass of a proton if the force is 1 x 10^-16 N and acceleration is 6 x 10^10 m/s²?

• 1.6 x 10^-27 kg

• 1.6 x 10^-26 kg

• 1.6 x 10^-28 kg

• 1.6 x 10^-25 kg
