Gravity

Front

What is gravity?

Back

Gravity is the force of attraction between two or more masses.

Front

How does distance affect gravity?

Back

The closer an object is to a mass, the stronger the pull of gravity it experiences.

Front

What happens to gravitational attraction if both masses increase and the distance decreases?

Back

The gravitational attraction increases.

Front

What is true about falling objects in a vacuum?

Back

All falling objects accelerate towards Earth at the same rate.

Front

What is a projectile?

Back

A projectile is an object that is being pulled by gravity while also having a sideways force applied to it.

Front

How does gravity affect projectiles?

Back

Gravity pulls equally on objects that are in free fall and projectiles.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the stronger its gravitational pull.

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 the effect of air resistance on falling objects?

Back

Air resistance can slow down the acceleration of falling objects, but in a vacuum, all objects fall at the same rate.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravity only, with no other forces acting on it.
