If the speed is DECREASING, angle θ between the velocity and acceleration vectors is in the range of: 90° < θ ≤ 180°; that is, the tangential component points rearward of the motion. Shown below is an ...

Remember, acceleration is the same as gradient, and acceleration = velocity change ÷ time. Look at the graph. The acceleration of the vehicle in the first 10 seconds is: ...

Treat acceleration as a vector when there is another vector quantity, such as velocity or force, involved in a question. Forces need a size and direction, eg \(300 N\) to the left.

In this online engineering specialization, you will master the theories and concepts of spacecraft attitude dynamics through three main topic areas: Kinematics, Kinetics, and Control. Apply transport ...
