Track a Tank Shell With a Mirror and Polar Coordinates If the internet was your online physics textbook, The Slow Mo Guys would be writing a good number of those homework questions.
All I need is to determine the acceleration of a sliding car and I can get a value for the coefficient of kinetic friction between the tire and the road.
The motion of a ball falling on the surface of the Earth is caused by the same interaction as the moon orbiting the Earth. In particular, I want to know the height of the mountain and I want to check the trajectory of the cannon ball paths.
This says that the total force on an object (or football player) is equal to the rate of change of momentum. I can find that Thompson force by looking at his change in momentum in that same time interval.
Moving in a circle at a constant speed means there is indeed an acceleration.If we have an object moving in a circle, the acceleration is pointed towards the center of the circle and depends on two things: the angular velocity (ω) and the circular radius (r).
But you can only measure where something’s going, and how fast, if you manage to hit it again and again.Blackmore's lidar reads the velocity of the objects it detects: The things moving away from the vehicle are in red, those moving toward it are in blue.
