Acceleration, momentum, angular momentum, magnetic and electric fields Each of the examples above involves magnitude and direction.Remember: A vector is not the same as a scalar. (see Part 1 on MiLearn.com) . Scalars have magnitude only. For example, a speed of 35 km/h is a scalar ...
Vectors are quantities that are fully described by magnitude and direction. The direction of a vector can be described as being up or down or right or left. It can also be described as being east or west or north or south. Using the counter-clockwise fro
An object with a constant acceleration has an initial velocity of 36 m/s east. After 10 s, the object has a final velocity of 53 m/s southwest. A) Calculate the components of the acceleration vector. B) Calculate the acceleration a in m...
Some examples of vector quantities include velocity, acceleration, and force. How are the vector's direction and magnitude represented? How to Find the Magnitude of a Vector A vector is represented by an arrow. How does one find the magnitude of a vector? The magnitude or the strength of ...
The initial velocity is 50 i+80 k , with speed measured in feet per second. The spin of the ball results in a southward acceleration of 4 ft/s2, so the acceleration vector is a=-4 j-32 k. Where does the ball land and with what speed?
An independent method for determining the gravity acceleration vector is presented in the paper. This method is implemented using information obtained from the gyro-inertial and radar instrumentation.doi:10.1134/S0038094617070103Likhachev, V. NFedotov, V. P...

What direction does the acceleration vector point in uniform circular motion? How are the centripetal and tangential components of accleration produced in an object moving in a circular path? Does centripetal force change when radius changes?
Homework Statement Two forces, vector F 1 = (4i+ 6j) N and vector F 2 = (4i+ 8j) N, act on a particle of mass 1.90 kg that is initially at rest at...
