Exploring Balanced and Unbalanced Forces in Motion

What does Newton's first law of motion state about an object at rest?

• It will move unless acted upon by an unbalanced force

• It will stay at rest unless acted upon by an unbalanced force

• It will increase in speed automatically

• It will change direction unless acted upon by an unbalanced force

What results when two balanced forces act on an object?

• The net force is zero

• The object's speed increases

• The object changes direction

• The object moves in the direction of the stronger force

How is net force calculated when forces act in opposite directions?

• By multiplying the forces

• By adding the forces

• By dividing the forces

• By subtracting the forces

What is the role of friction in motion?

• It increases the speed of the object

• It acts in the same direction as motion

• It has no effect on motion

• It opposes the motion

What happens to an object at rest if a net force greater than zero is applied?

• It moves in the direction of the greater force

• It moves in the direction of the weaker force

• It remains at rest

• Its speed decreases

What occurs when an object in motion experiences a net force not equal to zero?

• It stops immediately

• It reverses direction

• It continues moving at the same speed

• It changes speed or direction

How do twin engines on a jet affect its motion?

• They decrease the jet's speed

• They cause the jet to move in the direction of the net force

• They have no effect on the jet's motion

• They cause the jet to move in random directions

How is speed calculated?

• Speed does not depend on time or distance

• Distance divided by time

• Time divided by distance

• Distance multiplied by time

What defines a balanced force?

• It changes the object's state of motion

• It increases the object's speed

• It does not change the object's state of motion

• It decreases the object's speed

What effect does an unbalanced force have on an object at rest?

• It has no effect

• It decreases the object's mass

• It keeps the object at rest

• It moves the object in the direction of the greater force
