Front

What are the units of length in the metric system?

Back

Millimeter, Centimeter, Meter, & Kilometer are the units of length in the metric system.

Front

What type of forces are acting when they are not equal and cause a change in motion?

Back

Unbalanced forces are those that are not equal and can cause an object to move.

Front

True or False: Forces can cause objects to move.

Back

True, forces can cause objects to change their state of motion.

Front

What type of forces are acting when they are equal and do not cause a change in motion?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What happens to an object in motion when no unbalanced forces act on it?

Back

An object in motion will continue to move at a constant velocity if no unbalanced forces act on it.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the greater the gravitational force it exerts.

Front

What is the effect of unbalanced forces on an airplane landing?

Back

Unbalanced forces act on an airplane during landing, causing it to decelerate and change direction.

Front

What is the metric unit for measuring mass?

Back

The kilogram (kg) is the metric unit for measuring mass.
