The reason a moving object slows down is that its force of motion gradually runs out.
The reason a moving object slows down is that its force of motion gradually runs out.
A 12-kg object is moving on a rough, level surface, in a decelerated motion (slowing down to a stop). The friction force on it is a constant 3.60 N. What is the magnitude of its acceleration? a. 0.2 b. 0.3 c. 3.3 d. 2.3
A truck runs into a pile of sand, moving 1.6 m as it slows to a stop. The magnitude of the work that the sand does on the truck is 6.0×105J. Determine the magnitude of the average force that the sand exerts on the truck. Did the sand do positive or negative work? How does the magnitude of the average force change if the stopping distance is doubled? Assume that the work that the sand does on the truck remains...
Does a force applied to an object always produce motion? What can you figure out about the forces on an object just by observing its motion? If no forces are acting on a body, can the body be in motion? Explain.
For an object moving in uniform circular motion a) What is the direction of the centripetal force (Fc) b) What is the direction of its acceleration? c) What is the direction of its instantaneous velocity?
a person runs with an initial velocity of 5.0m/s. then he slows down at a rate of -1.2 m/a square over a period of 3 seconds
with reason please. Velocity and Acceleration Vectors An object is moving with an initial velocity along the x-axis and a constant acceleration in the second quadrant of the x-y plane as shown. Which one of the following statements about the subsequent motion of the object is true? (a) The velocity of the object never changes magnitude. (b) The velocity of the object never changes direction. (c) The direction of the velocity of the object is never the same as that...
I need help with the questions for Force Graphs and the questions for The Robot Moving Company on the physics lab. PHY213 Physics I PHY213 Online Lab 03 Lab 03: Forces and Motion Whoa! That's long way down PURPOSE In this experiment we will investigate the action of Forces and the resulting motion. THEORY Scalars are quantities that have only magnitude. Vectors are quantities that possess both magnitude and direction. Vectors, must be treated with direction in mind. Forces are...
An asteroid is moving along a straight line. A force acts along the displacement of the asteroid and slows it down. The asteroid has a mass of 4.2× 104 kg, and the force causes its speed to change from 7100 to 4500m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 2.3× 106 m determine the magnitude of the force.
An asteroid is moving along a straight line. A force acts along the displacement of the asteroid and slows it down. The asteroid has a mass of 5.4× 104 kg, and the force causes its speed to change from 6500 to 4500m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 2.4× 106 m determine the magnitude of the force.
A force Fx=4x+12 (in N, with x in m) acts on an object in one-dimensional motion. Find the work done by that force in moving an object from x = 0 to x = 9.0 m .
