... 3. Seat belts and air bags save lives by reducing the forces exerted on the driver and passengers in an automobile collision. Cars are designed with a “crumple zone” in the front of the car. In the event of an impact, the passenger compartment decelerates over a distance of about 1 m as the front o ...

... downward acceleration. Eventually you reach a point where the air resistance equals your body weight. This is known as terminal speed and would be well over 100 mph for a human body. To allow you to land without hurting yourself you deploy your parachute. This greatly changes the resultant force suc ...

Force
... Force - a push or a pull– it is the “thing” that causes accelerations. Note: This is a very abstract concept. We can never really talk about acceleration without stating the “thing” that caused the acceleration For example: The acceleration due to gravity The acceleration on the baseball due to the ...

Acceleration Characteristics for Circular Motion
... of seconds it takes me to go around once. This is called the frequency of rotation since it describes how frequently I complete a cycle. The frequency of an object’s motion is the number of times that it goes around a circle in a given unit of time. The symbol for frequency is “f” (easily confused w ...

Momentum - SCHOOLinSITES
... To increase the momentum of an object, it makes sense to apply the greatest force possible for as long as possible. The forces involved in impulses usually vary from instant to instant. For example, a golf club that strikes a golf ball exerts zero force on the ball until it comes in contact with it; ...
