Forces, Densities, and Gravitational Attraction

Front

What is elastic potential energy?

Back

Energy stored in an object when it is stretched or compressed.

Front

What direction will a skateboard move if a girl jumps off it facing east?

Back

The skateboard will move west.

Front

Which item requires the largest applied force to move: a picture frame, an empty bookshelf, a television, or a toaster oven?

Back

The television because it has the largest mass.

Front

What season is experienced in location Z when the Earth is at Position C in its orbit around the Sun?

Back

Winter.

Front

How should a 5 g sample of an element with specific physical properties be classified?

Back

As a metalloid.

Front

What is the definition of gravitational attraction?

Back

The 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 density?

Back

Density is the mass of an object divided by its volume.

Front

How do you calculate the density of an object?

Back

Density = Mass / Volume.

Front

What is the relationship between mass and gravitational attraction?

Back

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

Front

What happens to the gravitational force between two objects if the distance between them increases?

Back

The gravitational force decreases.
