5 days ago · Our projectile motion calculator is a tool that helps you analyze parabolic projectile motion. It can find the time of flight, but also the components of velocity, the range of the projectile, and the maximum height of flight. Continue reading if you want to understand what projectile motion is, get familiar with the projectile motion ...
4 days ago · In general terms, rotating a point with coordinates ( 𝑥, 𝑦) by 90 degrees about the origin will result in a point with coordinates ( − 𝑦, 𝑥). Now, consider the point ( 3, 4) when rotated by other multiples of 90 degrees, such as 180, 270, and 360 degrees.

1 day ago · Definition: Moment of a Force. The moment of a force ⃑ 𝐹 acting on a body, taken about point 𝑂, is given by 𝑀 = ⃑ 𝑟 × ⃑ 𝐹, where 𝑟 is the position vector of 𝐴, the point of application of force ⃑ 𝐹. In this definition, we see that the coordinate system has been chosen such that its origin coincides with the point about which we take the moment.
