Balanced and Unbalanced Forces

The video tutorial explains the concepts of balanced and unbalanced forces, providing definitions and examples for each. It discusses how forces affect motion, including the roles of friction and gravity. The tutorial also covers how to calculate net forces with examples and explains diagonal forces. Finally, it provides instructions for practice problems to reinforce learning.

What is a characteristic of a balanced force?

• It changes the direction of an object.

• It causes acceleration.

• It results in constant speed or no motion.

• It always acts in the same direction.

Which scenario is an example of a balanced force?

• A ball rolling down a hill.

• A book resting on a table.

• A person running.

• A car accelerating on a highway.

What happens when you push a box with equal and opposite forces?

• The box moves in the direction of the stronger force.

• The box remains stationary.

• The box accelerates.

• The box moves in a circular path.

Which of the following is an example of an unbalanced force?

• A person standing still.

• A book lying on a table.

• A car moving at a constant speed.

• A skateboard being pushed.

Why does a rolling chair move when pushed?

• Because the force applied is less than friction.

• Because the force applied is greater than friction.

• Because gravity is stronger than the push.

• Because air resistance is negligible.

How do you calculate the net force when two forces act in opposite directions?

• Add the two forces together.

• Subtract the smaller force from the larger force.

• Multiply the two forces.

• Divide the larger force by the smaller force.

If two forces of 5 Newtons and 7 Newtons act in the same direction, what is the net force?

• 2 Newtons

• 0 Newtons

• 12 Newtons

• 35 Newtons

What is the direction of the net force if 5 Newtons act to the right and 7 Newtons act to the left?

• To the right

• Downwards

• To the left

• Upwards

When forces act diagonally, what is the resulting motion?

• The object moves in a straight line.

• The object remains stationary.

• The object moves diagonally.

• The object moves in a circular path.

For a force to be considered balanced, what must be true?

• Forces must be equal and opposite.

• Forces must be unequal and opposite.

• Forces must be unequal and in the same direction.

• Forces must be equal and in the same direction.
