Forces, Energy and Motion Review

Front

What is the force that ultimately slows a roller coaster to a stop?

Back

Friction is the force that opposes motion and slows objects down.

Front

What are the two quantities measured in Newtons?

Back

Force and weight are both measured in Newtons.

Front

What is a Newton in terms of its derived units?

Back

A Newton is defined as Kg m/s², which comes from Newton's second law of motion.

Front

What is the SI unit used to measure weight?

Back

The SI unit for weight is Newtons.

Front

How do you calculate momentum?

Back

Momentum is calculated as the product of mass and velocity (p = m * v).

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F = m * a, where m is mass and a is acceleration.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as KE = 1/2 mv².

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, commonly gravitational potential energy (PE = mgh).

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass * gravity (W = mg).

Front

What is the principle of conservation of energy?

Back

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