PPT-Tides Gravity Remember, gravity is an invisible force of attraction between two objects.

What celestial object is attracted to the Earth The Moon What celestial object is the Earth attracted to The Sun Effect of the moon on the Earth The Moons gravity also pulls on the Earth but because the Earth is solid it doesnt seem to respond. Mr. McMartin. Beta Pod Science. Question:. Have you ever seen a video of astronauts on the moon? They bounce around like beach balls even though they wear big, bulky spacesuits. Why is leaping on the moon easier than leaping on earth?. High or Low - What Causes Tides?. Study Jams Video. What Are Tides?. Tides are the daily . rise. and . fall. of Earth’s . waters. on its coastlines. . As the tide comes . in. , the level of water on the beach . Tides. Tides Are the Longest of All Ocean . Waves, hence they are . Long waves. Tides Are Forced Waves Formed by Gravity and . Inertia. They are responsible for the rise and fall in sea level.. Tides . Gravity. Gravity is a force that for us is always directed downwards. But to say that gravity acts 
downwards is not correct. Gravity acts down, no matter where you stand on the Earth. It is 
better to say that on Earth gravity pulls objects towards the center of the Earth. So no matter 
where you are on Earth all objects fall to the ground. By Emily Weil. 9/10/09. Science Standard 3- The Physical Setting. Indicator 5.3.6- Demonstrate that things on or near Earth are pulled towards it by Earth’s gravity.. Taken from: . http://www.indianastandards.org/standardSummary.asp?Subject=sci&Grade=5. Parker MacCready, January 2011. Reference: . Admiralty Manual of Tides. , . Doodson. & Warburg, 1941, His Majesty’s Stationery Office. Orbital Force Balance. Tides are forced by the sun and moon, with similar physics. The Moon’s forcing is about twice that of the sun.. May 2013. What is a TIDE?. Rise and fall in ocean levels. Most observable at the coastlines. What is a TIDE?. 2 High tides and 2 Low tides occur daily. Approx. 6 1/2 hours apart. What causes TIDES?. Tides. Tides are the daily changes in the elevation of the ocean surface. Tides are the daily rise and fall of the Earth’s waters on its coastlines.. Tides are caused by the interaction of the Earth, the moon and the sun.. May 2013. What is a TIDE?. Rise and fall in ocean levels. Most observable at the coastlines. What is a TIDE?. 2 High tides and 2 Low tides occur daily. Approx. 6 1/2 hours apart. What causes TIDES?. EQ: What changes an object’s motion?. Friction and Gravity. What happens when you jump on a sled on the side of a snow-covered hill?. What happens at the bottom of the hill?. Friction and Gravity. Why does the sled’s motion change on the side of the hill and then again at the bottom?. Newton’s Law of Universal Gravitation. Newton Did not discover gravity, but he did discover gravity was universal. In other words, everything pulls on everything else.. States:. Every object attracts every other object with a force that for any two objects is directly proportional to the mass of each object, and indirectly proportional to the distance between them.. Honors Physics . Zero Gravity Cats!. Universal Gravitation. ALL. objects attract each other with a force of gravitational attraction. Gravity is universal. . This . force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers. . their highest point of the day and fall to their lowest point . every 12.5 hours. . The tides result from the rotation of Earth on its axis as gravity . from the moon and the sun pull on Earth and its water. Think . What are tides?. Tides are the daily changes in the level of ocean water.. What causes tides?. Tides are caused by the difference in the gravitational force of the sun and the moon.. What is tidal force?.
