Year 10 Science - Energy

Energy is...

• The ability to do work

• The ability to wear a shirt

• The ability to go bezerk

• If you touch it, it will hurt.

Kinetic energy is...

• energy of a moving object

• stored energy

• gravitational energy

• black holes

Kinetic Energy =

• 0.5 × mass × velocity²

• 0.5 × mass × velocity

• mass × velocity × height

• 0.25 × mass × velocity²

Gravitational Potential Energy =

• mass × gravity × height

• mass × height × velocity

• mass² × height × gravity

• mass × gravity × mass

Mass is measured in...

• Kilograms (kg)

• Newtons (N)

• Joules (J)

• Pounds (lbs)

Force is measured in...

• Kilograms (kg)

• Newtons (N)

• Joules (J)

• Midichlorians

Velocity should be measured in...

• Meters per second (m/s)

• Kilometers per hour (km/h)

• Joules (J)

• Bransons (B)

Acceleration should be measured in...

• Meters per second squared (m/s²)

• Meters per second (m/s)

• Newtons per second (N/s)

• Flame stickers

Newton's first law is best described by...

• Things that move stay moving, things that are stopped stay stopped.

• Things that are speeding up are accelerating.

• Things that are moving will eventually stop.

• A textbook on Physics.

A good example of Newton's first law is...

• A car slowing down due to friction.

• A car speeding up due to engine force.

• An astronaut floating near a space station.
