Forms of Energy Quiz

Study Notes

Types of Energy

Energy associated with an object in motion is called kinetic energy.

Measurement Units

Electrical energy is measured in units called joules or kilowatt-hours.

Newton's Laws of Motion

Newton’s First Law of Motion states that an object at rest remains at rest, and an object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Newton’s Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, often expressed as F=ma.

Motion Measurement

The measurement of the magnitude and direction of movement is called velocity.

Energy Generated by Heat

Energy that heat generates is known as thermal energy.

Potential Energy

The potential energy of an object at a higher position above the ground on Earth is known as gravitational potential energy, calculated based on height and mass.

Scalar Measurement

A scalar measures quantities that have magnitude only, such as temperature, time, and mass, without directional components.

Work and Energy Transfer

Work is measured in terms of energy transfer when an object moves, calculated as the product of force and displacement in the direction of the force (W=F·d).

Change in Momentum

The change in momentum is measured using the impulse-momentum theorem, which states that the change in momentum is equal to the impulse applied to the object.
