Balanced and Unbalanced Forces in Real-Life Scenarios

The video tutorial introduces the concepts of balanced and unbalanced forces in physics. It presents several scenarios involving a rock, gravity, normal force, friction, and air resistance to illustrate these concepts. The tutorial explains how forces can be balanced, resulting in no net force, or unbalanced, leading to a net force and potential acceleration. Each scenario is analyzed to determine the presence of a net force, helping viewers understand the dynamics of forces in different situations.

What is the net force acting on the rock in the first scenario?

• 0 N

• 5 N upwards

• 5 N downwards

• 10 N upwards

In the second scenario, what balances the 2 N force applied by the character?

• Normal force

• Friction

• Gravity

• Air resistance

What is the net horizontal force in the third scenario?

• 1 N to the right

• 1 N to the left

• 3 N to the right

• 2 N to the left

In the fourth scenario, what is the net force acting on the rock?

• 5 N upwards

• 4 N downwards

• 0 N

• 1 N upwards

What additional force is introduced in the fourth scenario?

• Magnetic force

• Air resistance

• Friction

• Normal force

In the final scenario, what is the net force direction?

• Downwards

• Left

• Right

• Upwards

How many newtons of force are applied to the right in the final scenario?

• 2 N

• 3 N

• 4 N

• 5 N

What is the total force opposing the 4 N push in the final scenario?

• 1 N

• 2 N

• 3 N

• 4 N

Which force is not balanced in the final scenario?

• Horizontal force

• Gravity
