Force Test Honors

Front

What does the size of the gravitational force between two objects depend on?

Back

The masses of the objects and the distance between them.

Front

What property explains why a coin falls into a cup when a card is quickly pulled away?

Back

Inertia.

Front

If a feather and a rock are dropped at the same time without air resistance, what will happen?

Back

They will fall at the same rate.

Front

What are two forces on the same object that are equal and opposite called?

Back

Balanced forces.

Front

How does the inertia of a 4.0 kg ball compare to that of a 2.0 kg ball?

Back

The inertia of the 4.0 kg ball is twice as great.

Front

Define inertia.

Back

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

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces do.

Front

What is the formula for calculating gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air.
