Objects are added to the box to make it much heavier

The worker is replaced with someone stronger.

The worker pushes the box over an uneven or rough floor

Objects are removed from the box to make it much lighter

Orientation of magnets

Strength of magnets

Distance between magnets

Mass of the magnets

Gravity is an attractive-only force that pulls objects towards other objects.

Magnetism between Earth and the moon is possible due to the composition of metals within Earth’s core.

Friction is a contact or non-contact force that increases in strength as distance decreases.

The greater the mass of an object, the greater the force of its gravity on other objects.

As distance increases, the strength of the force would increase.

As distance increases, the strength of the force would weaken

The strength of the force would increase and decrease due to other factors.

The strength of the force would not change, because it is not dependent on distance

Force A is the frictional force known as water resistance that pulls the swimmer backward.

Force A is the applied force the swimmer uses to propel themselves through the water

Force B is the normal force that is equal to and cancels out the force of gravity pulling the swimmer.

Force B is the gravitational force pulling the swimmer towards the Earth’s surface

The forces are unbalanced because the net forces equal zero

The forces are balanced because the net forces do not equal zero.

The forces are balanced because the net forces equal zero.

The forces are unbalanced because the net forces do not equal zero.

Kinetic energy increases with mass and velocity.

Kinetic energy decreases with mass and velocity.

Kinetic energy is not affected by mass.

Kinetic energy only depends on velocity.

It is stored in objects at rest.

It represents motion and the ability to cause change.

It cannot be converted to other forms of energy.

It is only present in living things.
