newtons law

What happens when an object experiences an unbalanced net force?

• Its mass decreases.

• Its velocity remains constant.

• It accelerates.

• It enters a state of equilibrium.

What is inertia?

• The force that causes an object to accelerate.

• An object's tendency to resist changes in its state of motion.

• The amount of matter in an object.

• The force exerted by gravity on an object.

How is the force of gravity (weight) on an object calculated, and what are its standard units?

• Mass divided by acceleration (m/a), measured in kilograms.

• Mass multiplied by acceleration due to gravity (mg), measured in Newtons.

• Force divided by mass (F/m), measured in meters per second squared.

• Mass multiplied by velocity (mv), measured in kilograms per second.

What forces act on a stationary box resting on the ground?

• Only the force of gravity.

• The force of gravity and the normal force.

• The force of gravity and the tension force.

• Only the normal force.

What is a characteristic of the tension force in an ideal rope?

• It is a fixed force that does not change.

• It always acts downwards.

• It adjusts to counteract the pulling force.

• It is only present when the rope is breaking.
