Gravity

Front

What is gravity?

Back

Gravity is a force of attraction between two objects that is directly related to their masses and inversely related to the square of the distance between their centers.

What happens to a projectile's motion when it is in free fall?

Back

When a projectile is in free fall, it is accelerated downwards due to gravity, and its horizontal motion remains constant.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is free fall?

Back

Free fall is the motion of an object when only the force of gravity is acting on it.

Front

How does air resistance affect falling objects?

Back

Air resistance opposes the motion of falling objects, causing them to fall slower than they would in a vacuum.

Front

What is terminal velocity?

Back

Terminal velocity is the constant speed reached by an object when the force of gravity is balanced by air resistance.

Front

If two objects are dropped from the same height in a vacuum, what will happen?

Back

Both objects will hit the ground at the same time, regardless of their masses.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force between two objects increases with greater mass and decreases with greater distance.

Front

What is projectile motion?

Back

Projectile motion is the curved path an object follows when it is thrown or propelled near the Earth's surface, influenced by gravity.

Front

What is the formula for gravitational force?

Back

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