How is distance different from displacement?

Distance is a scalar quantity that measures the total path length traveled by an object, regardless of direction.

Displacement is a vector quantity that measure the change in position of an object with a direction.

Rearrange the equation to make distance the subject: 

(final velocity)2 – (initial velocity)2 = 2 × acceleration × distance


distance = (final velocity)2 – (initial velocity)2 / 2 × acceleration

A person starts running in a straight line from point AA. They run 80 meters to point B, turn around, and run back past point A to point C, which is 20 meters beyond the starting point.

  1. What is the total distance traveled by the person?
  2. What is the person's displacement from the starting point?

Total distance is: 80m+80m+20m=180m

The displacement is: 20m

You are conducting an experiment to determine which of two car models, Car A and Car B, is safer in a frontal collision. To ensure a fair comparison, you maintain consistent testing conditions for both vehicles.

1. Identify the dependent variable, the independent variable, and at least three control variables in this experiment.

Dependent Variable:

  • Injury severity of crash test dummies (e.g., measured by the damage sustained by the dummies, such as head trauma, chest deflection, etc.)

Independent Variable:

  • Type of Car (Car A vs. Car B).

Control Variables:

  • Speed of Impact: Ensure both cars are tested at a consistent collision speed, such as 50 km/h.
  • Type of Collision: Both cars are subjected to the same type of frontal collision at a specific angle.
  • Test Dummies: Use the same model and configuration of crash test dummies in both cars.
  • Safety Features: Verify that airbags, seatbelts, and other safety systems are fully operational and deployed similarly in both cars.
  • Load and Weight: Keep the load inside the car constant, simulating the same number of passengers or equivalent weight.

All Formula One circuits have a speed trap. The speed trap is found on a long, straight section of a Formula One track. It is used to measure the maximum speed of the cars over the race.

As he enters the straight, Carlos Sainz is travelling at 69.4m/s. He undergoes constant acceleration along the straight. When he reaches the speed trap 9.59s later his maximum velocity is recorded as 91.7m/s.

QUESTION) Calculate the distance he travelled in this time. Give your answer to three significant figures.












Answer: distance = 772 (3s.f.)


SOLUTION: 

acceleration = change in velocity/time taken

acceleration = (91.7 – 69.4) ÷ 9.59

acceleration = 22.3 ÷ 9.59

acceleration = 2.325338

distance = (final velocity)2 – (initial velocity)2/ 2 x acceleration

distance = ((91.7)2 – (69.4)2) ÷ (2 × 2.325338…)

distance = (8408.89 – 4816.36) ÷ 4.650677

distance = 3592.53 ÷ 4.650677

distance = 772.4745

Therefore: distance = 772 (3s.f.)
