A student claims that people typically walk at 6 m/s. a) State whether or not you agree with this claim and explain your reasoning. b) Suggest a factor that can affect the typical speeds of a person walking. Part (a) The student’s claim is incorrect because 6 m/s is too fast. The typical speed that people walk at is about 1.5 m/s.
Speed cameras are used to measure a vehicle's speed Speed cameras are used to find out if a motorist is travelling faster than the speed limit for the road. The camera takes two photos of the vehicle.
The student’s claim is incorrect because 6 m/s is too fast. The typical speed that people walk at is about 1.5 m/s. Part (b) Some factors that can affect the typical speeds of a person walking are: The terrain might be wet, rocky or steep. The age of the person. The fitness of the person. The length of the walk or journey.
Newton's first law expresses the principle of inertia: the natural behavior of a body is to move in a straight line at constant speed. A body's motion preserves the status quo, but external forces can perturb this. The modern understanding of Newton's first law is that no inertial observer is privileged over any other.
The first law of motion, also known as the law of inertia, is one of the three laws formulated by Sir Isaac Newton in his groundbreaking work Philosophiæ Naturalis Principia Mathematica. This law states that an object at rest will remain at rest, and an object in motion will continue moving in a straight line at a constant speed, unless acted ...
Back in 1687 Sir Isaac Newton wrote three laws about motion, which basically are: 1st Law: Force is needed to change an object's velocity. 2nd Law: F = m a. 3rd Law: Every action has an equal and opposite reaction. They have wide use today (unless we are dealing with speeds close to the speed of light, or very small things like atoms).

2 days ago · Newton's laws of motion are three physical laws that can be considered as the foundation for classical mechanics. They describe the relationship between a body, the forces acting on it, and its motion in response to those forces. Forces are the bread and butter of Newtonian mechanics. Though they're not always the easiest way to think about the world, everything in classical ...
