HUMPTY DUMPTY ENGINEERING CHALLENGE #1 23/24

Front

What is the purpose of vehicle airbags?

Back

They are designed to cushion the force of a collision.

Front

How is momentum calculated?

Back

Momentum = mass × velocity.

Front

Which object has more momentum if Object A has a mass of 100 kg and Object B has a mass of 5 kg, both moving at the same velocity?

Back

Object A has more momentum.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

Which has the most kinetic energy: a caught baseball, a turtle swimming, or a parked car?

Back

A turtle swimming.

Front

What happens to total momentum during a collision?

Back

Total momentum remains the same during a collision.

Front

If a bicycle weighs 20 kg and is traveling at a speed of 10 meters per second, what is its momentum?

Back

200 kg-m/sec.

Front

What is the formula for kinetic energy?

Back

Kinetic Energy = 1/2 × mass × velocity².

Front

What is the unit of momentum?

Back

The unit of momentum is kg-m/sec.

Front

What is the relationship between mass and momentum?

Back

Momentum increases with an increase in mass if velocity remains constant.
