How do you find the normal force
between a table with a mass of 35 kg and
the floor?
(Assume that normal force and gravity are
the only two vertical forces.)
Your answer:
The normal force is the same
number - 35 kg.
Multiply the mass by the coefficient
of friction.
Multiple the mass by gravitational
acceleration (g = 9.8 m/s²)
The normal force is zero because
the table isn't moving vertically.
The normal force is 9.8 N because it
is on Earth.
Clear answer
Consider a human who weighs 862 N on Earth. What is the person's mass on Earth? And what is the same person's mass on Mars, where the acceleration due to gravity is 3.7 m/s2?

- Imagine a book sitting on a horizontal table. One of the forces acting on a book is a normal force exerted by the table (let's call it action). What force does form the Newton's 3rd law pair (reaction)? Normal force exerted on the Earth by the book. Normal force exerted on the table by the book. Normal force exerted on the table by the Earth. Normal force exerted on the Earth by the table.arrow_forwardYou hang a 1.0 kg mass from a spring scale like we did in a class demo. But this time, instead of holding your hand still so that the acceleration is zero, you let your arm drop so that the mass accelerates downward at 5.2 m/s2. What force (how many Newtons) will the spring scale read while this acceleration is happening assuming you are standing on the surface of Earth, so that the force on the 1.0 kg mass due to gravity is 9.8 Newtons?arrow_forwardWhat if we have air resistance in the environment?

- Consider applying Newton's second law to a man riding an elevator (perhaps to calculate his acceleration). Which of the following forces must be considered? Choose all that apply. The force that the man's head exerts on his neck. The force of gravity on the elevator. The force the elevator cable exerts on the elevator car. The force that the elevator floor exerts on the man's feet. The force that the man's feet exert on the floor of the elevator. The force of gravity on the man.arrow_forwardWhat is the mass of an object that weighs 250 N on the surface of the Earth where the acceleration due to gravity is 9.8 m/s²? What about the mass of a 250 N object on the Moon (g = 1.7 m/s?)? On Mars (g = 3.7 m/s²)?arrow_forwardI have a question for elevator problems: Newton's law states that there is always an equal and opposite force. But for elevator problems, if it accelerates upwards... we say that the normal force is greater than the gravitational force. So is Newton's third law still applied here and if so how? Because technically the opposite force is not equal in magnitude for it to be able to acceleratearrow_forward
- If you are floating in outer space, and you need to change your motion in order to get back to the safety of your spaceship. You throw your shoe away with a force of 320 Newtons, which means the shoe pushes back on you with a force of 320 Newtons. If you have a mass of 61 kg, what is the magnitude of your acceleration?arrow_forwardImagine a landing craft approaching the surface of Callisto, one of Jupiter's moons. If the engine provides an upward force (thrust) of 3048 N, the craft descends at constant speed; if the engine provides only 2057 N, the craft accelerates downward at 0.39 m/s2. What is the weight of the landing craft in the vicinity of Callisto's surface? What is the mass of the craft? What is the magnitude of the free-fall acceleration near the surface of Callisto?arrow_forwardYour car just ran out of gas and you are stuck in the middle of the road holding up traffic. Luckily, your friend Reuben is in the car with you so you decide to ask for his help in pushing the car to the side of the road. Reuben, being very lazy and having just taken PHYS 151, explains to you that it’s useless to try pushing the car to get it moved to the side of the road. His reasoning is that when you exert a force on the car, the car will exert an equal and opposite force in return according to Newton’s third law of motion. These two opposing forces would cancel each other resulting in a net force of zero and no possible acceleration – therefore, it’s better to just sit back, relax, and wait for AAA. Do you agree with his assessment? Why or why not? If you don’t agree with him, how would you convince him otherwise to help you?arrow_forward
