3A/B PE STUDIES – REVISION NOTES Conservation of linear momentum when both objects are moving * In conservation of linear momentum the momentum of both objects before impact is not lost but remains the same for the combined momentum of both objects after impact. Example When playing snooker‚ once struck‚ the white “cue ball” will contain a certain amount of momentum. This is determined by its mass and how fast its travelling. When this ball makes contact with the black ball the total momentum

Try to make the occupants change velocity in the same way as the car does An inertial-belt is used to keep the occupant moving at the same velocity as the car at all times therefore preventing them from moving with their own inertia and sharing it with the car. Cushion the surfaces of the passenger compartment Airbags are used to cushion blows or impacts with the car for occupants in case of accidents. There are also no or barely any sharp edges inside a car that can harm

The Scientific Revolution was a big change throughout Europe; it changed the medieval views of the world. It started with medieval views as the framework‚ The Renaissance stimulating science‚ navigational problems needing new instruments‚ and scientific methodology. This seemed to be a big impact on the world. Religiously‚ this challenged some views from the Bible. In Philosophy‚ It started a new way of thinking‚ thus shows both were impacted by the Scientific Revolution. Religious: .Nicolaus

As soon as you get on the roller coaster you will experience an a Inertia Jerk. Then you will be going up a steep hill when the only thing that will be affecting you will be gravity. You will also be moving at a constant speed while going up the hill of the roller coaster. Then when you reach the top of the roller coaster

PHYSICS 1 MIDTERM EXAM REVIEW #2 1. A 6.0-N force and an 8.0-N force act concurrently on a point. As the angle between these forces increases from 0° to 90°‚ the magnitude of their resultant (1) decreases (2) increases (3) remains the same 2. A car increases its speed from 9.6 m/s to 11.2 m/s in 4.0 s. The average acceleration of the car during this 4.0-second interval is (1) 0.40 m/s2 (3) 2.8 m/s2 (2) 2.4 m/s2 (4) 5.2 m/s2 3.

Section A How does the engine size(capacity) of a motor car relate to the acceleration of the car? Hypothesis: The acceleration of a car will increase if the size(capacity) of the engine increases. The car with the biggest engine capacity will take the fastest to reach the velocity of 60km/h from rest position. Method: 1) Arrange to use three different hatchback cars with different engine capacities‚ but
