IPC - Physics Semester Exam Review

Front

What is electrical force?

Back

Electrical force is the attraction or repulsion between charged particles. It is one of the four fundamental forces of nature.

Front

What is a parallel circuit?

Back

A parallel circuit is an electrical circuit where components are connected across common points or junctions, providing multiple paths for current to flow.

Front

How does gravity change with distance?

Back

As the distance between two objects increases, the gravitational pull between them decreases.

Front

What does it mean for an object to accelerate?

Back

An object accelerates when there is a change in its velocity, which can occur due to a change in speed or direction.

Front

What is nuclear energy?

Back

Nuclear energy is the energy released during nuclear fission or fusion, particularly from radioactive materials.

Front

What is the difference between contact forces and non-contact forces?

Back

Contact forces require physical contact between objects (e.g., friction, tension), while non-contact forces act at a distance (e.g., gravitational, electrical, magnetic forces).

Front

What is the formula for calculating gravitational force?

Back

The formula for gravitational force is F = G * (m1 * m2) / r^2, where F is the force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated using the formula KE = 1/2 mv^2, 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, such as gravitational potential energy, which depends on height.
