F=ma

Dr. Forrester introduces Newton's laws of motion, focusing on the second law, which states that force equals mass times acceleration. Through practical examples, such as comparing a playground ball and a bowling ball, and an experiment using a spring scale, the video demonstrates how more force is needed to move heavier objects. The video encourages viewers to apply these principles in everyday life and scientific investigations.

Who was the scientist that laid the groundwork for the modern study of physics?

• Galileo Galilei

• Niels Bohr

• Albert Einstein

• Sir Isaac Newton

According to Newton's Second Law, what happens when a force acts on a mass?

• The object changes color

• The object disappears

• The object remains at rest

• Acceleration is produced

Which of the following requires more force to move the same distance?

• A bowling ball

• A feather

• A paperclip

• A playground ball

In the experiment with the spring scale, how much force was needed to lift the block of wood?

• 8 newtons

• 4 newtons

• 2 newtons

• 6 newtons

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

• F = m * a

• F = m - a

• F = m / a

• F = m + a
