Gravity

Front

What is Newton's Law of Universal Gravitation?

Back

It states that every object in the universe attracts every other object, and the force of attraction is affected by the mass of the objects and the distance between them.

What happens to the normal force when an additional bowling ball is placed on a table?

Back

The normal force increases to balance the additional weight of the bowling ball, but if the table cannot support the extra weight, it may break.

Front

What is Gravitational Attraction?

Back

It is the force that pulls two objects towards each other; the greater the mass, the greater the attraction, and the farther apart the objects, the weaker the attraction.

Front

Define Mass.

Back

Mass is the amount of matter in an object, typically measured in kilograms or grams.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, which is dependent on the mass of the object and the acceleration due to gravity.

Front

What is the acceleration due to gravity on Earth?

Back

Approximately 9.81 m/s².

Front

If air resistance is not a factor, how do all falling objects behave?

Back

All falling objects accelerate towards Earth at the same rate, regardless of their mass.

Front

What is the difference between mass and weight?

Back

Mass is a measure of the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is the formula for calculating weight?

Back

Weight (W) = Mass (m) × Acceleration due to gravity (g).

Front

What is the effect of distance on gravitational attraction?

Back

The greater the distance between two objects, the weaker the gravitational attraction between them.
