Newton's second law – pulling a block on a surface

PhysicsForces & DynamicsAges 15–16

Pull a block of mass m with force F along a horizontal or inclined surface with friction μ. Watch the force vectors (F, P, N, Fms), the acceleration a = (F − Fms − P·sinα)/m, and a real-time velocity-time graph v(t). Drag the F slider right in the simulation, or drag the block to reposition it.
