Potential and Kinetic energy 2

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, commonly gravitational potential energy, which depends on height and mass.

Front

When does a roller coaster have maximum kinetic energy?

Back

A roller coaster has maximum kinetic energy at the bottom of each hill.

Front

How does height affect gravitational potential energy?

Back

Gravitational potential energy increases with height; the higher an object is, the more potential energy it has.

Front

What factors determine gravitational potential energy?

Back

Gravitational potential energy depends on the height and mass of the object.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between kinetic energy and speed?

Back

Kinetic energy is proportional to the square of the speed; if speed doubles, kinetic energy increases by a factor of four.

Front

What is the potential energy of an object at ground level?

Back

The potential energy of an object at ground level is considered to be zero.

Front

How do two objects at the same height but different masses compare in potential energy?

Back

Two objects at the same height have different potential energies if their masses are different; the heavier object has more potential energy.

Front

What is the formula for gravitational potential energy?

Back

The formula for gravitational potential energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
