Questions in physics

[Open]What is the mass of an object if a force of 34 N produces an acceleration of [tex]4 \, \text{m/s}^2[/tex]?

[Open]Gravitational pull must be measured in units of _______.

[Open]If an object is accelerating to the right, then the net force on the object must be directed towards the right. True or False?

[Open]Amusement parks are a great place to see Newton's laws of motion in action. Choose your favorite ride and describe the parts of the ride that illustrate each of Newton's laws of motion. You are only required to give a written description; however, if you would like, you may draw and label a picture in addition to the paragraph explanation. Please be sure to look at the rubric to see exactly what you are expected to include.

[Open]Ina shoots a large marble (Marble A, mass: 0.08 kg) at a smaller marble (Marble B, mass: 0.05 kg) that is sitting still. Marble A was initially moving at a velocity of 0.5 m/s, but after the collision, it has a velocity of -0.1 m/s. What is the resulting velocity of Marble B after the collision?

[Open]What is displacement divided by time?

[Open]What position will have the smallest magnitude of vertical velocity?

[Open]A bolt falls off an airplane high above the ground. How far does the bolt have to fall before its speed reaches 100 m/s (about 200 miles per hour)? Ignore air friction in your calculation.

[Open]Explain why your weight would be less on the Moon than on Earth, even though your mass would not change. Use the law of universal gravitation in your explanation.

[Open]How many newtons of force would 200 grams apply? What would be the mass of an object that weighs 7 N on Earth? If an object weighs 450 N, how much does it weigh in pounds?
