Types of Forces Gravitational Attraction Gravitational attraction depends on two factors: mass and distance. Compare the gravitational force between different planets and their sun.
Types of Forces Weight and Mass The Mars Phoenix Lander weighs about 3, 400 N on Earth. It weighs about 1, 300 N on Mars. If the dog weighs 60 N on Earth, what would he weigh on Mars and the moon?
Balanced and Unbalanced Forces Net Force The change in motion of an object is determined by the net force acting on the object. What is the net force for each situation?
Balanced and Unbalanced Forces Which of these three arrows below represents the correct amount of net force of the above two force arrows?
Newton’s Laws of Motion Newton’s Second Law Suppose that four dogs pull a sled carrying two people. How can the pictures be completed to represent answers to the two different questions?
Newton’s Laws of Motion Action-Reaction Forces How can the illustration of the dogs be completed to represent Newton's Third Law of Motion?
Newton’s Laws of Motion What Makes a Bug Go Splat? Splat! A bug has just flown into the windshield of an oncoming car. The car must have hit the bug much harder than the bug hit the car, right?
