force and motion

What is the definition of a magnet?

an object that attracts certain other materials like iron and steel.

What is magnetism?

the force exerted by a magnet and a force that can act at a distance

What is a magnetic field? 

is the region around a magnet in which the magnet exerts a force.

What is magnetic force?

is a force that can act at a distance with the interaction of a north and south pole.

How can you increase the strength of a magnetic force?

by increasing the strength of the magnet or move the magnets closer into the field

How can you decrease the strength of a magnetic force?

by decreasing the strength of the magnet or by moving the magnets further outside of the field.

Where is a magnet, magnetism the strongest?

-The poles

List some examples of objects that use a magnet to function.

• Refrigerator 

• Doorbells

• Microwave

• Radio 

• Credit card

What causes magnetism to work on Earth?

The circulation of iron and nickel in earth's core creates a magnetic north and south pole. Because of earth's magnetic poles, a compass needle will point north.

Magnetic field lines run….

north to south

What is an electric field?

a region around a charged object where the objects electric force is exerted on other charged objects.

What is an electrical force?

is the attraction or repulsion between electric charges

How do you increase the the electrical force?

by increasing the number of charged particles or move the particles closer into the field

How do you decrease the electrical force?

You decrease the number of charged particles or move the particles further outside the field.

What way do the arrows point on a proton

point out

What way do the arrows point on an electron

points inward

List examples of where electrical forces are used.

Anything that requires electricity like batteries, static electricity, and electricity.

What is the definition of gravity?

the force by which a planet or other body draws objects toward its center

What is gravitational force? 

is the force that attracts any 2 objects with mass within a field

How can you decrease the amount of gravitational force?

by decreasing the amount of  mass in the  objects or move the objects farther apart.

How can you increase the amount of gravitational force?

by increasing the mass of the object or move the objects closer together.

what is a gravitational field?

the region of space around an object in which all other objects experience an attractive force.

What way do Earth gravitational field line point

they point inward

List examples of objects that exert gravitational force.

• Any planet in the solar system and the sun. Anything that has mass

What is the difference between weight and mass?

Weight can change depending on where you are and mass stays the same

What is a force

a push or a pull

Give an example of 2 types of forces. 

• Gravity

• Normal force

• Electrical force

• Magnetic force

what is mass?

The amount of matter in your body

what is weight

The amount of gravitational pull you have on the earth
