Car Collisions: Energy and Forces

What is the most significant type of energy involved in car collisions?

• Kinetic energy

• Potential energy

• Thermal energy

• Chemical energy

What happens to the kinetic energy of vehicles during a collision?

• It is entirely lost

• It is converted into sound and heat

• It remains unchanged

• It is converted into potential energy

Which force helps to slow down vehicles during a collision?

• Gravitational force

• Magnetic force

• Frictional force

• Electrostatic force

According to Newton's first law, what causes a moving object to change its motion?

• Its own inertia

• An external force

• Its mass

• Its speed

What does Newton's third law state about the forces during a car collision?

• For every action, there is an equal and opposite reaction

• The force is proportional to the mass and acceleration

• An object in motion stays in motion

• The force is inversely proportional to the distance
