A spherical mass on the end of a string is spinning in a vertical circle about point P. Which of the forces acting on the mass is the centripetal force when the mass is in position A? The tension in the string. A The force of gravity (weight). The force of drag (air resistance). None of the above are correct. Which of the forces acting on the mass contribute to the centripetal...
QUESTION 2 Remember that centripetal force and centripetal acceleration is the special name we give to the inwards force and acceleration that causes (forces) the object to move in a circle In the case of gravity where gravity causes a planet or satelite or star to orbit around another larger body, then gravity force is the centripetal force Centripetal force is the net force, and centripetal acceleration is the net acceleration. What is the centripetal acceler ation of a planet...
The direction of the centripetal force is always in the same direction a. as the centripetal acceleration vector b. as the velocity vector c. that an object would have if the centripetal acceleration suddenly stopped d. as the direction of motion of the object In this question, "constant in direction" refers to a fixed direction such as east or west. For uniform circular motion, the acceleration vector is a. changing in magnitude but constant in direction b. constant in magnitude...
Does the force of gravity
alone provide the means for the centripetal force, is this why they
are equal ? For explaining why there is no normal force, could you
see it as the astronaut having the same acceleration as the ship
and so the relative acceleration = 0, so it's under the illusion
almost of having no acceleration so there's no force ? Please !! If
you have different reasoning please share. I'm just trying to wrap
my head...
Which of the following would count as a centripetal force? (Choose All That Apply) The force of gravity causing the earth to travel in a circular path around the sun The tension in a rope as you swing a yo-yo in a circle over your head The force of friction from the seat on you as you travel around a curve while driving a car The normal force acting on a car as it drives in a circle All of...
(b) For an object in uniform circular motion, derive the expression which relates centripetal force to speed. (5 marks] (c) A person swings an object around in a circle on the end of a steel wire, at a constant speed completing one revolution every 1.9 s. The object has a mass of 1.75 kg. The radius of the circle is 2.3 m. (i) Draw a diagram indicating the direction of the following vectors: velocity, centripetal acceleration, centripetal force. [3 marks]...
A ball rolls down a hemi-spherical bowl. Circle the correct response: The centripetal force is... (a) The normal force (b) The net force of the vertical component of gravity and the normal force
What is the angle formed between the vectors of centripetal acceleration and centripetal force? Pro Select one a. 180 degrees b. 90 degrees 30 degrees d. 0 degrees
A block sits on the floor. (a) What is the magnitude of the frictional force on it from the floor? (b) If a horizontal force of 5 N is now applied to the block, but it does not move, what is the magnitude of the frictional force on it? (c) If the maximum value fs,max of the static frictional force on the block is 10 N, and you apply a 12 N force, what is the magnitude of the frictional...
