π Topic Summary
Crime scene investigation worksheets help you apply scientific principles, particularly from physics, to analyze evidence found at a crime scene. These worksheets often involve calculations related to trajectory, speed, force, and the properties of matter. By completing these exercises, you'll understand how investigators use physics to reconstruct events and solve crimes.
π Part A: Vocabulary
Match the terms on the left with their definitions on the right:
| Term |
Definition |
| 1. Trajectory |
A. The transfer of energy that causes a change in momentum. |
| 2. Force |
B. The path followed by a projectile flying or an object moving under the action of given forces. |
| 3. Velocity |
C. The rate at which someone or something moves in a specific direction. |
| 4. Momentum |
D. Mass in motion; calculated as mass multiplied by velocity ($p = mv$). |
| 5. Friction |
E. The resistance that one surface or object encounters when moving over another. |
π Part B: Fill in the Blanks
Complete the paragraph using the words provided: gravity, speed, impact, angle, blood spatter.
Analyzing ___________ can provide clues about the events that occurred at a crime scene. The ___________ at which a projectile strikes a surface affects the shape of the stain. __________ causes objects to fall towards the Earth, influencing projectile trajectories. The ___________ of a moving object is important for calculating momentum. The force of ___________ can also affect the appearance of evidence.
π€ Part C: Critical Thinking
Imagine you are a crime scene investigator. You find a bullet lodged in a wall. Describe how you could use physics principles to determine the shooter's possible location. What measurements would you need to take, and what calculations would you perform?
