Energy in Motion 2

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy that 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, often associated with gravitational force.

Front

How is total mechanical energy defined?

Back

Total mechanical energy is the sum of kinetic energy and potential energy in a system.

Front

What happens to potential energy at the lowest point of a pendulum?

Back

At the lowest point of a pendulum, all potential energy is converted into kinetic energy, resulting in 100% conversion.

Front

What is the formula for calculating kinetic energy?

Back

The formula for calculating kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.

Front

What does the term 'direction' refer to in physics?

Back

Direction refers to the line or path along which something moves, points, or faces.

Front

How does force affect the motion of an object?

Back

Force causes an object to accelerate in the direction of the applied force, according to Newton's second law of motion.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is the significance of a graph in understanding motion?

Back

A graph can visually represent the relationship between distance, time, and speed, helping to analyze an object's motion.

Front

What is the unit of energy in the International System of Units (SI)?

Back

The unit of energy in the SI system is the Joule (J).
