IPC Fall Semester Exam Review - Physics

Front

What is an inelastic collision?

Back

An inelastic collision is a type of collision where momentum is conserved, but kinetic energy is not. The objects do not stick together after the collision.

Front

What happens to the speed of an object during a specific interval if it is changing?

Back

The speed of the object is changing during the interval D-E.

Front

What are the four fundamental forces of nature?

Back

The four fundamental forces of nature are Electromagnetism, Gravity, Strong Nuclear Force, and Weak Nuclear Force.

Front

How can you make an electromagnet stronger?

Back

You can make an electromagnet stronger by adding more coils of wire to the nail.

Front

At which point is kinetic energy greatest in a given scenario?

Back

Kinetic energy is greatest at point X.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

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 mv².

Front

What is the difference between elastic and inelastic collisions?

Back

In elastic collisions, both momentum and kinetic energy are conserved. In inelastic collisions, momentum is conserved, but kinetic energy is not.

Front

What is the formula for calculating gravitational force?

Back

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

Front

What is the role of the strong nuclear force?

Back

The strong nuclear force holds protons and neutrons together in the nucleus of an atom.
