Exploring Net Force Concepts in Edpuzzle

Mrs. Bullock explains the concept of net force, also known as the sum of forces, using a tug of war example. She demonstrates how to calculate net force by comparing the forces exerted by two teams. Initially, the blue team wins due to a stronger force. When forces are balanced, the net force is zero, resulting in no movement. Adding more members to the red team creates an unbalanced force, leading to their victory.

What is another term used for net force?

• Total energy

• Gravitational pull

• Kinetic energy

• Sum of forces
