Newton's Laws review - rollercoaster

To calculate the speed of the coaster, you need to know the distance it travels and

• the time it takes

• mass of the cars

• height of the hills

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

NGSS.MS-PS2-2

The roller coaster car changes direction due to

• balanced forces

• an unbalanced force applied

• an action and reaction force

Tags

NGSS.MS-PS2-2

You will want a lot of friction

• at the start of the roller coaster

• as the roller coaster turns

• at the end of the roller coster

A roller coaster has a mass that requires ____ to accelerate

• force

• friction

• momentum

Tags

If the force on the mass of the roller coaster is increased, then the __ will also increase.

• acceleration

• friction

• direction

If the action force is the rails of the roller coaster on the cart. The reaction is

• the cart moves forward

• the force of the cart on the roller coaster

• the cart has momentum
