Albert presses a book against a wall with his hand. As Albert gets tired, he exerts less force, but the book remains in the same spot on the wall Classify each force on the book as increasing, decreasing, or not changing in magnitude when Albert

Consider a box sitting on the floor. If you applied 275 Newtons of force horizontally to the right and the frictional force was 25 Newtons, What would be the magnitude and direction of the net force?

For the vectors in the figure, with a = 12, b = 9.0, and c = 15 what are (a) the magnitude and (b) the direction of a * b, (c) the magnitude and (d) the direction of a * c, and (e) the magnitude and (f) the direction b * c?

Why do the planets move in fixed orbits around the sun?

Work is defined as the use of force to move an object in the direction of that force and is equal to the force times the distance the object moved. How do energy and power relate to work?

A cylindrical metal rod is 2.40 m long and 5.99 mm in diameter. The resistance between its two ends (at 20oC) is 1.38 * 10-3 Ω. (a) What is the material? (b) A round disk, 2.24 cm in diameter and 1.20 mm thick, is formed of the same material.

Two cars are moving in the same direction in parallel lanes along a highway. At some instant, the velocity of car A exceeds the velocity of car B. Does that mean that the acceleration of car A is greater than that of car B? Explain.

A motorist enters a freeway at 45 km/h and accelerates uniformly to 99 km/h. From the odometer in the car, the motorist knows that she traveled 0.2 km while accelerating.

What is the Coriolis Force?

Einstein's general theory of relativity made or allowed us to make predictions about the outcome of several experiments that had not yet been carried out at the time the theory was first published.
