Energy and Collisions Quiz 14

What happens to a truck's kinetic energy as its mass increases?

• It decreases

• It stays the same

• It increases

• It becomes zero

What type of energy is produced due to friction in Newton's cradle?

• Light energy

• Sound energy

• Thermal energy

• Electrical energy

What causes the sound energy produced in Newton's cradle?

• Friction between the strings
  

• The collision between the balls

• The movement of the balls in the air

• The weight of the balls

In Newton's cradle, what energy transformation occurs when the ball is lifted and then released?

• Thermal to kinetic energy

• Potential to kinetic energy

• Kinetic to sound energy

• Thermal to potential energy

What happens to the energy of moving balls in Newton's cradle over time?

• It increases continuously

• It gets destroyed completel

• It decreases gradually due to collisions and transforms into other forms

• It stays constant without any change

A car has more kinetic energy than a truck when both are moving at the same speed.

• true

• false

In Newton's cradle, energy is destroyed during collisions.

• true

• false

A bicycle moving at the same speed as a car causes less damage in a collision because of its smaller mass.

• true

• false

The amount of energy before a collision is always equal to the amount of energy after a collision.

• true

• false

During a collision, some kinetic energy is converted into sound and thermal energy.

• true

• false
