Why is it harder to get a cart full of potatoes moving than one that is empty?
The full cart has greater mass and greater inerita. A larger force is needed to overcome the inerita.
How does mass affect the inertia of an object?
The greater the mass the greater the inerita. The greater the inerita the greater the force needed to overcome the inerita.
What is needed in order to cause an object at rest to move, or an object in motion to change its direction or speed?
An outside force
The tendency of an object to resist a change in motion is known as
inertia
______ is a measure of the amount of matter in the object.

weight
______ is expressed in newtons (N).
weight
_______ is expressed in grams (g), kilograms (kg), or milligrams (mg).
mass
__________ is a measured using a spring scale.

a) mass b) weight
weight
_________ is a measure of the gravitational force on an object.

a) mass b) weight
weight
__________ is always constant no matter where the object is located.

a) mass b) weight
mass
What is the only way to change the mass of an object
Change the amount of matter that makes up the object
On newton equal to the weight of an object that has
a mass of 100g on Earth
The SI unit of weight is the
newton
The SI unit of mass is the
kilogram
The amount of matter in an object is its
mass
Why can you express the volume of the gold nugget measured by this method in cubic units?
One mL is equal to 1 cubic cm, you can express the volume of the water displaced by the object in cubic centimeters.
How can you find the volume of an irregularly shaped object such as a gold nugget?
Drop the gold nugget in water in a graduated cylinder and measure the volume of water displaced.
What 3 dimensions are needed to find the volume of a rectangular solid?
The 3 dimensions are length x width x height.
The volume of solid objects is commonly expressed in ___________ units.
cubic
To measure the volume of water in a graduated cylinder, you should look at the bottom of the curve at the surface of the water called _________________.
meniscus
Things with ___________ cannot share the same space at the sane time.
volume
What is volume?
Volume is a measure of the size of a body or region in three-dimensional space.
What is matter?
