Force and Newton's Laws: Newton's Second Law of Motion

The video tutorial explores the concept of force in relation to Newton's second law of motion. It compares the impact of a piece of paper and a baseball, both accelerating at 10 meters per second squared, to illustrate how mass affects force. The tutorial further examines how increasing the baseball's acceleration to 20 meters per second squared results in a greater force, reinforcing the relationship between mass, acceleration, and force.

Which object would deliver a softer impact when both are accelerating at the same rate?

• A rock

• A basketball

• A piece of paper

• A baseball

What is the formula that represents the relationship between force, mass, and acceleration?

• Force equals acceleration divided by mass

• Force equals mass divided by acceleration

• Force equals mass plus acceleration

• Force equals mass times acceleration

If a piece of paper has a mass of 0.02 kg and accelerates at 10 m/s², what is the force it exerts?

• 2.5 kg m/s²

• 0.02 kg m/s²

• 2 kg m/s²

• 0.2 kg m/s²

How much force does a baseball exert if it has a mass of 0.25 kg and accelerates at 10 m/s²?

• 1 kg m/s²

• 2.5 kg m/s²

• 0.25 kg m/s²

• 5 kg m/s²

What happens to the force of a baseball if its acceleration increases to 20 m/s²?

• The force halves

• The force doubles

• The force decreases

• The force remains the same
