AP Physics 1: Gravity Flashcard

Front

What is the amount of matter in an object?

Back

Mass

Front

Calculate the gravitational force between two objects when they are 0.750m apart. Each object has a mass of 5.00kg.

Back

2.96x10^-9 N

Front

Does the moon fall?

Back

Yes, the moon is falling around the earth due to its tangential velocity.

Front

What is the gravitational pull between two masses of 8000 kg and 1500 kg that are 1.5 m apart?

Back

0.0003 N

Front

Without gravity, what would happen to stars, planets, and all objects in the universe?

Back

They would move in a straight line.

Front

Define gravity.

Back

Gravity is the force that attracts two bodies towards each other, proportional to their masses and inversely proportional to the square of the distance between them.

Front

What is the formula for 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 the centers of the two masses.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as the product of mass and gravitational acceleration (W = m * g).

Front

What is inertia?

Back

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

Front

Explain the concept of tangential velocity.

Back

Tangential velocity is the linear speed of an object moving along a circular path, directed along the tangent to the path.
