Force, Mass, and Acceleration Concepts

The video tutorial explains how to calculate mass, acceleration, and net force using Newton's second law. It covers examples involving a car, a ball, a papaya, and a crate, demonstrating the application of the formula F = ma. The tutorial emphasizes unit conversion and the importance of consistent units in calculations.

What is the formula used to calculate the mass of an object when force and acceleration are known?

• F = ma

• m = F/a

• a = F/m

• F = m/a

If a car accelerates from rest to a velocity of 40 m/s in 10 seconds, what is its acceleration?

• 8 m/s²

• 6 m/s²

• 4 m/s²

• 2 m/s²

Given a net force of 200 N and an acceleration of 4 m/s², what is the mass of the car?

• 75 kg

• 50 kg

• 100 kg

• 25 kg

What is the mass of an object if a net force of 200 N results in an acceleration of 4 m/s²?

• 100 kg

• 75 kg

• 50 kg

• 25 kg

What is the acceleration of a ball with a mass of 0.40 kg when hit with a force of 16 N?

• 40 m/s²

• 50 m/s²

• 30 m/s²

• 20 m/s²

How do you calculate acceleration when force and mass are known?

• a = F*m

• a = F-m

• a = F/m

• a = m/F

What is the acceleration of an object if a force of 16 N is applied to a mass of 0.40 kg?

• 40 m/s²

• 30 m/s²

• 50 m/s²

• 20 m/s²

What is the net force exerted on a 3.5 kg papaya with an acceleration of 2.2 m/s²?

• 7.7 N

• 5.5 N

• 8.8 N

• 6.7 N

If a papaya is pushed with a force resulting in an acceleration of 2.2 m/s², what is the formula to find the net force?

• F = m/a

• F = a/m

• F = m-a

• F = ma

What is the mass of a crate if a net force of 300 N causes an acceleration of 0.75 m/s²?

• 300 kg

• 200 kg

• 500 kg

• 400 kg
