Forces and Motion in a Rollercoaster

If you know the distance a rollercoaster travels and the time it takes on the track, you can calculate the

• speed

• acceleration

• motion

The roller coaster car begins to move due to

• Newton's first law of motion

• Newton's second law of motion

• Newton's third law of motion

Tags

NGSS.MS-PS2-1

The roller coaster car changes direction due to

• balanced forces

• an unbalanced force applied

• an action and reaction force

At the end of the rollercoaster ride, this force is needed because it resists motion between two surfaces that are pressed together.

• gravity

• velocity

• friction

A rollercoaster has a mass that requires _ to accelerate

• force

• friction

• momentum

If you increase the force on the mass of the roller coaster, then this will also increase.

• acceleration

• friction

• direction

When does a roller coaster car accelerate?

• only when it turns

• only when it stops at the end

• only when it speeds up down the hill

• both when it turns or changes it speed

The resistance of an object to changes in motion

• gravity

• inertia

• reference point

• speed

Before the rollercoaster ride starts and the net force is zero is an example of

• unbalanced forces

• gravity

• balanced forces

• contact force
