What does the formula F = ma represent? A. Force is equal to mass times acceleration. B. Force is equal to acceleration divided by mass. C. Force is equal to mass divided by acceleration. D. Force is E. qual to the square of acceleration times mass. ...
When spring is extended or compressed from its mean length, the spring exerts a force to resist the deformation in the spring is called a spring force. The spring force acts always in the opposite direction of the displacement (compression or extension) in the spring.Answer and Explanation: To...
What is the formula for electrostatic force?Answer and Explanation: The formula to be used F = K (q1q2)/d2 Where K = 8.988 x 109 Nm2/C2 q1 = Charge on 1st electron = 1.602 x 10-19 q2 = charge on 2nd electron = 1.602 x 10-19 d = 1 m Replace the different values in the ...
All we've done is calculate Gary's average velocity; we haven't addressed the subject of instantaneous velocity, a phenomenon that puts its own twist on the formula broken down above.) Velocity Formula Calculator Average Velocity: Time Period: Output Unit: Calculate Displacement Closing ...

Once Young’s modulus (the modulus of longitudinal elasticity) is known, you can calculate the stress from the strain amount. σ = (material-based constant E) ×ε— Formula 5 Let’s Obtain the Stress (the Applied Force) From the Strain Amount ...
Centripetal and centrifugal forces are two terms used to describe the physics of circular motion — but only one of them is real. The centripetal force keeps an object moving in a circle and is always pointed toward the center of that circle. For instance, the gravitational force of the sun...
Force is everywhere and it comes in a variety of sizes, directions, and type. We can define Force as the push or pull of an object. Learn Force definition, unit & types of Force with solved examples.
The conversation also briefly touches on the formula for power being equal to torque multiplied by angular velocity, and the limitations of real motors and engines. Ultimately, it is suggested that redefining the problem and considering the necessary force to provide a given resistance m...
