en an object undergoes non-uniform circular motion, its acceleration vector can be broken into a radial component and a tangential component. O True O False 10 For non-uniform circular motion, the radial component of the object's acceleration represents the lengthening or shortening of the object's velocity vector. True False 11.1 1 m circular motion, the tangential component of th For non-unifor e object's acceleration represents the change in the direction of the object's velocity vector. True O False
Consider an object in uniform circular motion. A.) If the trajectory and the mass of the object are unchanged, but the centripetal force is doubled, is the object's speed multiplied by a factor of 1, square root of 2, 2, or 4? B.) If the mass of the object is halved and the radius of the circle quadrupled, while keeping the mass of the object the same, is the object's speed multiplied by a factor of1, square root of 2,...
The acceleration vector of a particle in uniform circular motion a) points outward from the center of the circle. b) points toward the center of the circle. c) is zero. d) points along the circular path of the particle and opposite the direction of motion. e) points along the circular path of the particle and in the direction of motion.
10) When a car makes a turn at a constant velocity, on a flat level road, does the car experience a net force while making the turn? (Be careful Canvas my not have the same order for the answers) No, because the frictional force is equal to the centripetal force. No, because the speed is constant. Yes, it is the frictional force and is directed towards the center Yes, it is the frictional force and is directed outward away from...
A particle with a charge of +4.20 nC is in a uniform electric field È directed in the negative x direction. It is released from rest, and after it has moved 6.00 cm, its kinetic energy is found to be + 1.50 × 10-6 J. (a) what work was done by the electric force? (b) What was the change in electric potential over the distance that the charge moved? (c) What is the magnitude of E? (d) What was the...
You drive on a banked road in a roughly circular path. Besides any component needed to keep your car moving, what is the direction of the frictional force on your car? a. Up along the incline b. Down along the incline c. horizontally inward d. horizontally outward e. it depends on the speed at which you drive
Example 7.7 Buckle Up for Safety Goal Calculate the frictional force that causes an object to have a centripetal acceleration. Problem A car travels at a constant speed of 31.5 mi/h (14.1 m/s) on a level circular turn of radius 55.0 m, as shown in the bird's-eye view in Figure 7.13a. What minimum coefficient of static friction, µs, between the tires and the roadway will allow the car to make the circular turn without sliding? Strategy In the car's free-body...
The impulse of an object is 1 a. the product of (the peak force applied to an object) x (time interval during which the force acts). 2 b. the product of (the average force applied to an object) x (time interval during which the force acts). 3 c. the average force applied to an object for a period of 1 sec. 4 d. the peak force applied to an object for a period of 1 sec. 5 e. the total...
