U2L4 Review Flashcardizz (Gravity)

Front

What is a force field?

Back

A model that describes the force on an object if it were placed in any location in space, used to predict the strength and direction of noncontact forces.

Front

What is an orbit?

Back

A path that an object follows as gravitational forces act on it, specifically the path an object in space follows around another object due to gravitational forces.

Front

What does a force field model?

Back

The force on an object if the object were placed in any location in space.

Front

What are gravitational forces?

Back

Always attractive, noncontact forces between objects that have mass.

Front

Why doesn’t a feather fall at the same rate as an apple?

Back

Air resistance reduces an object’s downward acceleration and affects objects differently.

Front

What is gravity?

Back

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

Front

What is mass?

Back

The amount of matter in an object, which affects the strength of the gravitational force it experiences.

Front

What is weight?

Back

The force exerted by gravity on an object, calculated as mass times the acceleration due to gravity.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force increases with greater mass and decreases with greater distance between objects.

Front

What is air resistance?

Back

A type of friction that acts against the motion of an object moving through air, affecting its acceleration.
