The formula for calculating the force is F = ma. If the mass is 5 kg and the acceleration is 3 m/s², what is the force? A. 8 N B. 15 N C. 25 N D. 10 N 相关知识点: 试题来源: 解析 B。本题考查物理公式 F = ma 的应用。将质量 5kg 和加速度 3m/s²代入公式可得力为...
Objects with larger gravitational mass will have a greater gravitational attraction to other objects. This attraction is generated by the gravitational field of each individual object with mass. When one object is present in the gravitational field of another, the force of attraction between the two...
12 m at a constant speed with a rope that weighs 0.8 kg/m. Initially the bucket contains 36 kg of water, but the water leaks at a constant rate and finishes draining just as the bucket reaches the 12 m level. How much work is done? Work = Force*Distance Force = Mass*Accelerati...
In summary, a man with a mass of 190 kg pushes a piano at a constant velocity down a ramp inclined at 15.8 degrees above the horizontal floor. The man's force can be calculated using the equation F=M*g*sin(theta), and resolving the force along and perpendicular to the inclined plane...
The simplified formula consists of three parts, representing contributions from different physical phenomena: added mass force and/or inertial force in inviscid flow, the force caused by the deformation of fluid and viscosity and the force caused by the convection of fluid with nonzero circulation. ...
