How do you determine the force on an object if there are multiple forces acting on it? What force would be required to accelerate a 1,100 kg car to 0.5 m/s^2? What is the value of gravitational acceleration? What is the formula of gravitational force?
Determine the restoring force of a pendulum that is pulled to an angle of 12.0 deg left of the vertical. The mass of the bob is 300.0 g. The length of a simple pendulum is 5 m and the mass of the bob at the end of the cable is 26 kg. The pendulum is pulled away from its equ...
Angular velocity and centripetal acceleration are related through the formula a = ω²r, where a is the centripetal acceleration, ω is the angular velocity, and r is the distance from the object to the axis of rotation. This means that the greater the angular velocity, the greater the cen...
Motion sensor systems (also called Inertial Measurement Units—IMUs) incorporating tri-axial accelerometers and magnetometers are increasingly being used in animal-attached tags to determine fine-scale (second to infra-second) movement of animals via dead-reckoning [33, 34], thereby allowing elucidatio...
Vector operations are used to analyze the motion of two-dimensional events, like the up and sideways motion of a cannonball. Learn how to do vector operations using components, using an example and explanation on how to break a vector into components. ...
The infrared spectrum is frequently used to determine what molecules exist in the atmosphere of a planet and how abundant they are. Earth-based telescopes equipped with infrared spectrometers can detect elements in the atmospheres of other planets and even planets around other stars. With these ...
Scientists study these features of the universe to determine its fate, whether it will continue to expand or at some point collapse in of itself. As the universe continues to expand, scientists used to think that gravitational forces give objects an attractive force between one another to slow ...
If there's still all that force exerted between the box and the track, why is it about to fall of the track? Maybe because the weight is bigger than the normal force, or there is no normal force.. But, i don't know how to determine the normal force in this prob...
How can you use mechanical advantage and velocity ratio to determine the efficiency of a lever? Why does an electric fan continue to rotate for some time after the current is switched off? Why is sin ? used in the torque formula while the work formula uses cos ? ?
These are not drawn to scale. Which of the following statements is always true, for any \theta? a. F_{f} + N = mg b. Why does centripetal force matter? How does mass and acceleration affect force? Determine the magnitude of the torque that the two forces F_1 and F_2 together ...
