A. the force of gravity on the mass due to the Earth and the force of gravity on the Earth due to the mass B. the contact force on the mass due to the table and the contact force on the table due to the mass C. the force of gravity on the mass due to the Earth and the contact table on the table due to the mass D. the force of gravity on the mass due to the Earth and the contact force on the mass due to the table E. the contact force on the mass due to the table and the force of gravity on the Earth due to the mass

Gravitational field vector

What is the weight of the following objects? to. A 3.5 kg hockey puck. b. A 7.5 kg bowling ball.

12. According to Newtons third law: The action force is equal in magnitude to the reactionforce and opposite in direction. The forces also act on different bodies. What does thisexplain?: a) It explains why the net force is always zero. b) It explains why the net force is not always zero. c) It explains why the Sun is much bigger than Earth. d) None of the above

Question answer

A mass sits at rest on top of a table. Which two forces are interaction pair forces and thus are equal and opposite? A. the contact force on the mass due to the table and the force of gravity on the Earth due to the mass B. the force of gravity on the mass due to the Earth and the contact force on the mass due to the table C. the force of gravity on the mass due to the Earth and the force of gravity on the Earth due to the mass D. the force of gravity on the mass due to the Earth and the contact force on the table due to E. the mass

While in space far from any gravitational body, a 120-kg astronaut pushes off a 2400 kg space vehicle. The contact lasts .25 seconds, after which the astronaut is traveling 1 m/s a) what's the magnitude of the pushing force?  b) what's the speed of the vehicle after the contact has ended? c) how is Newton's 3rd law demonstrated?

When you are in a car's passenger seat (on the right –US car), and the driver turns left, you are thrown against the car door. Your little nephew says there is a force pushing you out of the car. Explain what is really happening, using good physics.
