World Book’s Building Blocks of Science Gravity. ANSWERS: 1. True. 2. If there were no such thing as gravity you would fly up into the air and off into space. 3. The strength of gravity depends on distance and mass. 4. Weight is a measure of the pull of gravity on an object. 5. True. 6. The moon has less mass than Earth, so its gravity is weaker.
Physical Science Mass and Weight. Use the following formula to solve for weight: Weight (W) = Mass (m) x gravity (g) W = mg. Mass is measured in kilograms (kg) Gravity on earth is a constant: 9.8 m/s2 Weight is measured in Newton’s (1 N = 1 kg m/s2) Answer the following questions – show ALL WORK and UNITS. 1. Define Mass –.
Gravity – Student Worksheet Your weight is your mass and the gravitational pull of the planet or moon you are standing on. If you weighed yourself on Earth and then moved to the Moon you would find that you weighed more on Earth. This is because the Earth is much more massive than the Moon and has a stronger gravitational pull.
The first person to state clearly that all objects on Earth fall with the same acceleration was Galileo (1564 − 1642). He used experimental observation with mathematical argument to arrive at this. This acceleration, denoted by the letter g, is known as the acceleration due to gravity.
Worksheet 5.1 - Newton’s Law of Universal Gravitation. 1) Two students are sitting 1.50 m apart. One student has a mass of 70.0 kg and the other has a mass of 52.0 kg. What is the gravitational force between them? 5) The gravitational force between two objects that are 2.1x10-1 m apart is 3.2x10-6 N.
Gravity is an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein described gravity as a curve in space that wraps around an object—such as a star or a planet.
4 gru 2015 · Example: Calculate the force of gravity between two students with mass 55 kg and 45kg, and they are 1 meter away from each other. what is the acceleration due to gravity on asteroid e. Exercise: Calculate the force of gravity between Earth (mass = 6.0 x 1024 kg) and the moon (mass = 7.4 x 1022 kg). The Earth-moon distance is 3.8 x 108 m f.
