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.

What is an ANCAP rating and what does it stand for?
The Australasian New Car Assessment Program.
Assassing the safety of new cars.
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.
Total distance is: 80m+80m+20m=180m
The displacement is: 20m

If a car traveling at 20 m/s crashes into a solid barrier and comes to a stop in 0.5 seconds, what is the average deceleration experienced by the car? And this scalar or vector?
A) 40 m/s²
B) 20 m/s²
C) 10 m/s²
D) 80 m/s²

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:
Independent Variable:
Control Variables:
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.)
