Calculating Net Forces in Motion and Direction

The video tutorial explains how to calculate net force using examples. It covers the concept of force having both magnitude and direction, and demonstrates calculations for different scenarios: forces in the same direction, opposing forces, and forces with different magnitudes. The tutorial aims to help students understand how to determine the net force acting on an object.

What two characteristics does every force have?

• Magnitude and speed

• Weight and height

• Magnitude and direction

• Speed and direction

If two people are pushing in the same direction with forces of 29 N and 39 N, what is the net force?

• 68 N west

• 10 N east

• 10 N west

• 68 N east

When two forces are applied in opposite directions, how do you determine the net force?

• Divide the larger force by the smaller force

• Multiply the forces

• Subtract the smaller force from the larger force

• Add the forces

In the example where one person pushes with 30 N to the east and another with 29 N to the west, what is the net force and direction?

• 1 N east

• 1 N west

• 59 N east

• 59 N west

If two people are pulling with forces of 10 N and 41 N in opposite directions, what is the net force and direction?

• 51 N east

• 31 N east

• 31 N west

• 51 N west

What is the net force when two people pull with equal forces of 10 N each in opposite directions?

• 0 N

• 10 N east

• 10 N west

• 20 N east

In a tug of war scenario, if one side pulls with 41 N and the other with 10 N, what is the net force?

• 31 N towards the weaker side

• 51 N towards the weaker side

• 51 N towards the stronger side

• 31 N towards the stronger side
