Gravitational Forces

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

Why is gravity on the moon less than on Earth?

Back

Because the moon's mass is less than that of Earth.

Front

What happens to the pull of gravity as the product of two objects' masses increases?

Back

The pull of gravity increases.

Front

When placed at equal distances apart, which will have the greatest gravitational attraction?

Back

Two school buses, because they have greater mass compared to skateboards or bowling balls.

Front

What is scientific notation?

Back

A way of expressing numbers as a product of a number between 1 and 10 and a power of 10.

Front

Convert 52,300,000 into scientific notation.

Back

5.23 x 10^7.

Front

What is the effect of air resistance on falling objects?

Back

Air resistance can slow down the fall of lighter objects, but gravity pulls all objects down at the same rate in a vacuum.

Front

What did the student conclude when a bowling ball and an apple were dropped from the same height?

Back

Gravity pulls on both objects, causing them to fall at the same time.

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 of the objects, and r is the distance between their centers.

Front

What is the gravitational constant (G)?

Back

G is approximately 6.674 x 10^-11 N(m/kg)^2, a constant used in the calculation of gravitational force.
