Balanced and Unbalanced Forces

What is the relationship between force and motion?

• Force causes changes in motion.

• Motion causes changes in force.

• Force and motion are unrelated.

• Force is a type of motion.

What type of force is experienced by a skier skiing through flags in a race down the mountain?

• Balanced Force

• Unbalanced Force

• Frictional Force

• Gravitational Force

What is a force that causes an object to change its motion?

• Balanced Force

• Unbalanced Force

• Frictional Force

• Gravitational Force

What is the net force when two equal forces act in opposite directions?

• Zero net force.

• Two times the force in one direction.

• The sum of the two forces.

• One of the forces acting in the opposite direction.

How do balanced forces affect the motion of an object?

• They keep the object in its current state of motion.

• They cause the object to accelerate in the direction of the net force.

• They change the object's speed and direction continuously.

• They make the object come to a complete stop.

What is inertia?

• The tendency of an object to resist changes in its state of motion.

• The force that causes an object to accelerate.

• The speed of an object in a given direction.

• The mass of an object multiplied by its velocity.

How do unbalanced forces affect the motion of an object?

• They cause the object to remain at rest.

• They cause the object to accelerate or decelerate.

• They have no effect on the object's motion.

• They cause the object to move in a circular path.

What type of force is acting on a book sitting on a shelf?

What type of force is present when two ice skaters are moving in a straight line at a constant speed?

• Unbalanced Force

• Frictional Force

• Balanced Force

• Gravitational Force

What happens to an object at rest when balanced forces act on it?

• It remains at rest.

• It starts moving in the direction of the force.

• It accelerates in the opposite direction of the force.

• It changes shape.
