Balanced & Unbalanced Forces

The video tutorial explains Newton's First Law of Motion, focusing on balanced and unbalanced forces. It uses a horse as an example to illustrate how forces like gravity, reaction force, driving force, friction, and air resistance interact. When forces are balanced, an object remains stationary or moves at a constant velocity. Unbalanced forces cause acceleration or deceleration. The tutorial summarizes these concepts, emphasizing the relationship between force balance and motion.

What does Newton's first law of motion imply about an object with balanced forces acting on it?

• It will accelerate.

• It will increase in mass.

• It will remain stationary or move at a constant velocity.

• It will change direction.

In the example of the horse, what force opposes gravity to keep the horse from sinking into the ground?

• Friction

• Air resistance

• Reaction force

• Driving force

When a horse is moving at a constant velocity, which forces are balanced?

• Driving force and friction plus air resistance

• Driving force and reaction force

• Gravity and air resistance

• Driving force and gravity

What happens to the horse's motion when the driving force exceeds friction and air resistance?

• The horse stops moving.

• The horse accelerates.

• The horse maintains constant velocity.

• The horse moves backward.

What is the result of unbalanced forces acting on an object?

• The object will either accelerate or decelerate.

• The object will move at a constant velocity.

• The object will change its mass.

• The object will remain stationary.
