Science Court Inertia

What is Newton's First Law of Motion?

• An object at rest will suddenly move, and an object in motion will suddenly stop.

• An object does whatever gravity tells it to do.

• An object in motion will stay in motion and an object at rest will stay at rest.

What does friction do?

• Make things go faster than they normally would.

• Slow things down.

• It depends on the amount of gravity the object has.

Why don't things moving through outer space slow down?

• There is no gravity to stop them.

• There is not enough heat from the sun to warm them up and cause them to stop.

• There is no air in space, so there's no friction to slow them down.

What is the relationship between mass and inertia?

• The greater the mass, the greater its inertia.

• The greater the mass, the less its inertia.

• The less the mass, the faster its inertia

Jamie is testing to see how the surface will affect the distance a toy car travels. He is using a small car and a long ramp that is 10 cm high. Jamie puts different surfaces on the ramp, and then lets the car roll down the ramp. He measures how far the car travels from the bottom of the ramp.

What force do you think causes the car to roll the shortest distance on the surface?

• push

• gravity

• friction

What is inertia?

• The tendency of an object to keep doing whatever it is doing.

• The tendency of an object to start doing something it wasn't already doing.

• A property of gravity.

• A type of force.

• normal

• gravity

What was the mistake that Cramwood made?

• By adding tape to his BAAD, Cramwood decreased its mass and increased its inertia.

• By adding tape to his BAAD, Cramwood increased its mass and increased its inertia.

• He was so ridiculously good looking and everyone hated him and so Jenkins gave him a faulty BAAD.
