A horseshoe magnet is moved toward a pile of iron shavings. The iron shavings divide and attach to both ends of the magnet. How does the kinetic energy of the system change? A. Kinetic energy decreases because iron shavings move in the opposite direction of magnetic force.
B. Kinetic energy decreases because iron shavings move in the direction of magnetic force.
C. Kinetic energy increases because iron shavings move in the opposite direction of magnetic force.
D. Kinetic energy increases because iron shavings move in the direction of magnetic force.

Kinetic energy increases because iron shavings move in the direction of magnetic force.

Potential energy decreases, and kinetic and thermal energy increase.

Potential energy increases because movement is in the opposite direction of the magnetic field.

They seek a rail line not affected by friction.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
