Gravity + Magnets + KE/PE

Front

What is gravitational potential energy (PE)?

Back

The energy an object possesses due to its position in a gravitational field, calculated as PE = mgh (mass x gravity x height).

Front

What is kinetic energy (KE)?

Back

The energy an object has due to its motion, calculated as KE = 1/2 mv² (1/2 x mass x velocity squared).

Front

What does the PE vs. KE graph represent?

Back

It shows the relationship between potential energy and kinetic energy as an object moves, illustrating the conversion between the two forms of energy.

Front

What is the law of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.

Front

What is mass?

Back

The amount of matter (stuff) in an object.

Front

What is the SI unit for measuring force?

Back

Newtons (N).

Front

What is magnetic north?

Back

Magnetic north is the direction that a compass needle points, which is actually geographic south.

Front

At which point in a pendulum's swing is kinetic energy highest?

Back

At the lowest point of the swing.

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass, calculated as Weight = mass x gravity.

Front

What is the formula for gravitational force?

Back

F = G(m1*m2)/r², where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.
