John's grandfather clock has a pendulum that keeps the seconds. what does this graph say about the observed pattern of motion?

a) the pendulum swings with a constant velocity.

b) the vacillating periodic motion changes sign.

c) the pendulum displays a constant acceleration.

d) the oscilations show a variable rate of motion.

Option A: The pendulum swings with a constant velocity.

The pendulum is swinging back to center at position 2 m and time 8 sec.

grav forces affect all objects magnetic forces affect magnetic objects and electric currents

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
