How can we measure the volume of this

How can we measure the volume of this sample of water? Volume of the water can be measured by ________________ ______

What is volume? • The amount of space an object takes up 3 • UNITS = L or cm

Volume of liquids is determined by using a graduated cylinder Volume is measured with liters

Measure at the MENISCUS

V =73 m. L

V = 18 m. L

V = 294 m. L

V =6. 6 m. L

V =21. 5 m. L

How is Volume of a solid measured? V=Lx. Wx. H

• Example: • L =2 cm, W=1 cm, H=1 cm • V = L x W x H • V =2 cm x 1 cm • V = 2 cm 3

Example: V = ?

• V = L x W x H • V = 2 cm x 3 cm x 5 cm 3 • V = 30 cm

How can we measure the volume of this rock? Water Displacement = • to measure volume of an irregular shaped object • Use graduated cylinder • V = Volume of water with object – Volume of water without object

V = 9 – 7= 2 V = 2 m. L V 1 = 7 m. L V 2= 9 m. L

Example: V = 20 – 11. 5 V = 8. 5 m. L V 1 =11. 5 m. L V 2 = 20 m. L

What’s the volume? 150 ____m. L

What is the volume of the rock in the diagram to the left? How could we determine the mass of the rock? Triple beam balance

What is mass? What unit can be used to describe mass? Amount of matter that an object contains

When you hit a volleyball, it might hurt just a bit as it bounces off your hands to go sailing over the net. That's because, although a volleyball isn't very massive, the mass it does have makes it resist your effort to change its motion. Bowling balls, on the other hand, possess much more mass than volleyballs do. If you tried to knock a bowling ball over the net, you just might break your arm!

How is mass measured? TRIPLE BEAM BALANCE

Mass = 542 gm

Mass = 137. 4 gm

Mass = 25. 4 gm

Mass = 79. 4 gm

weight is a measurement of the gravitational force acting on an object Weight varies based on location, whereas mass is constant.

If your weight on Earth is 100 lbs, on the Moon it would be 16 lbs. If your mass on Earth is 65 Kg, your mass on the Moon would be 65 Kg
