In collisions and explosions, the…doyi (3)in doyi • 5 years agoWork and Energy7 Work and Energy 50m×9.8m/s2 ×0.10 = 7.0m/s. Suppose a constant force Fx acts in the +x−direction and causes an object to move a distance of ∆x. The work-done by the force is defined as W =fx∆x.…doyi (3)in doyi • 5 years agoLaws of motion 5 Newton’s Laws of Motion Dynamics, the study of how forces influence motion, is involved in understanding a wide range of phenomena.
