Egg Drop Physics

Why can adding a parachute lower the chances that your egg can break?

• Adding a parachute causes my device to fall faster, creating more kinetic energy.

• Adding a parachute causes my parachute to fall faster, decreasing kinetic energy.

• Adding a parachute causes my parachute to fall at a slower speed, decreasing kinetic energy..

Why do eggs break when they land on concrete?

• The egg's kinetic energy cannot pass through concrete, so i passes through the egg, causing it to break.

• The egg is harder than the concrete

• the egg is moving too slowly to bounce

• eggs don't break on concrete

What force is acting on your device, causing it to fall and build kinetic energy after it is released?

• The wind

• Mr. Phifer

• A push

• Gravity

Why can adding a parachute help slow your device?

• Parachutes are heavy and small

• Parachutes catch the air, creating resistance and slowing down how fast something falls

• Parachutes won't slow the device

• Parachutes catch the air, causing things to fall faster

What is potential energy?

• The energy that is determined by force

• The energy of a resting object, determined by how heavy it is and how far it has to fall

• The energy that is determined by speed

• the energy of gravity

How do I reduce potential energy?

• Make my device lighter

• Make my device faster

• make my device heavier

• give my device a parachute

What is kinetic energy?

• The energy of speed or motion

• The energy an object has at rest, based on it's mass and height

• the energy of height

• the energy of gravity

How do I decrease the amount of kinetic energy?

• I need a way to make my object heavier

• I need a way to increase the mass

• I need a way to slow the device down as it is falling

• I need a way to speed the object up
