Roller Coasters

The energy of motion:

• potential energy

• gravitational potential energy

• chemical energy

• kinetic energy

Energy determined by an object's position:

• chemical energy

• heat energy

• gravitational potential energy

• kinetic energy

The purpose of the highest hill at the start of a roller coaster ride is to:

• gain the most potential energy

• gain the least kinetic energy

• gain the least potential energy

• develop the most chemical energy

When a roller coaster takes off the down an incline (hill), it is converting:

• potential energy to chemical energy

• chemical energy to heat energy

• kinetic energy to potential energy

• potential energy to kinetic energy

A "G" refers to:

• the force of gravity exerted on your body

• the mass change of your body when exposed to gravity

• a decrease in your weight due to your mass

• an increase in your weight due to a decrease in gravity

The "thrill" of a roller coaster ride is a result of:

• the G forces on your body during the ride staying the same

• the lack of G forces exerted during the entire ride

• the constant changing of G forces throughout the ride

• the constant speed of the ride

The force that keeps an object moving in a circular or curved pass is:

• diagonal force

• universal force

• centripetal force

• gravitational force

If centripetal force is lost on an object travelling in a curved path, the object will:

• continue on the curved path

• continue moving on in a straight line

• stop completely

• change it's path back and forth from curved to straight to curved again

The tendency of an object to stay in motion or at rest is:

• force

• acceleration

• inertia

• velocity

An object's speed and direction:

• acceleration

• velocity

• displacement

• distance
