Forces & Motion CSA Review

Front

What is Newton's Cradle?

Back

A device that demonstrates the principles of conservation of momentum and energy through a series of swinging spheres.

Front

What happens when one sphere is lifted and released in Newton's Cradle?

Back

The last sphere on the opposite end swings up to nearly the same height as the lifted sphere, while the others remain still.

Front

State Newton's First Law of Motion.

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the formula for calculating net force?

Back

Net Force = mass x acceleration (F = ma).

Front

Define acceleration.

Back

The rate at which an object's velocity changes with time.

Front

What is the relationship between mass and acceleration according to Newton's Second Law?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is momentum?

Back

The product of an object's mass and its velocity (p = mv).

Front

Explain the concept of conservation of momentum.

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What happens during an elastic collision?

Back

Both momentum and kinetic energy are conserved.
