Gravitational force

What are Noncontact Forces?

• Objects fall to the ground because Earth exerts an attractive force on them.

• is an attractive force that exists between all objects that have mass

• force that one object can apply to another object without touching

• a region of space that has a physical quantity (such as a force) at every point

What is Gravity?

• A force that one object can apply to another object without touching

• is an attractive force that exists between all objects that have mass

• Objects fall to the ground because Earth exerts an attractive force on them

• a region of space that has a physical quantity (such as a force) at every point

What pulls things down?

• is an attractive force that exists between all objects that have mass

• Gravitational Force Objects fall to the ground because Earth exerts an attractive force on them.

• a region of space that has a physical quantity (such as a force) at every point

Everything in our solar system is held in orbit by the gravitational force created by the Sun

what does orbit means?

• the large round object that circles the Earth and that shines at night by reflecting light from the sun.

• the heavenly body in our solar system whose light makes our day and around which the planets revolve.

• the path an object travels around another object

• the orbit is another definition of gravity

• less

Mass is often measured in?

• kilograms

• Grams

you can find the gravitational acceleration by…. The force of gravity on objects on objects by the mass of the objects

• multiplying

• dviding
