Momentum key terms

momentum

Momentum is the product of an object's mass and its velocity, represented by the equation p = mv.

seat belt

A seat belt is a safety device in vehicles that restrains passengers, increasing stopping time and spreading forces during a collision.

Crumple Zone

A structural feature in vehicles designed to absorb energy during a collision, increasing the time taken for the impact.

Collision Time

The duration over which a collision occurs, which can affect the force experienced by occupants in a vehicle.

momentum

Momentum is the product of an object's mass and its velocity, represented by the equation p = mv.

force

Force is defined as the rate of change of momentum, indicating how momentum changes over time.

momentum

Momentum is defined as the product of an object's mass and its velocity, represented by the equation p = mv.

change in momentum

Change in momentum refers to the difference in momentum of an object before and after an event, such as a collision.

momentum

Momentum is defined as the product of an object's mass and its velocity, represented by the equation p = mv.

vector quantity

A vector quantity is a physical quantity that has both magnitude and direction, such as momentum.

momentum

Momentum is defined as the product of an object's mass and its velocity, represented by the equation p = mv.

force

Force is related to the rate of change of momentum, indicating how quickly momentum changes when a force is applied.

momentum

Momentum is defined as the product of an object's mass and its velocity, represented by the equation p = mv.

impulse

Impulse is the change in momentum of an object when a force is applied over a period of time, calculated as the product of force and time.
