Dynamics (Force or Newton’s 2nd Law) Problems. Dynamics (Force) problems ask you to relate motion to the forces causing it. Note that the word “force” isn’t always used explicitly in the statement of the problem. You know many forces such as gravity, tension, and normal force that are present even if not listed in the problem.

Only the forces going in the direction of the motion will contribute any work! Given: When s = 0.6 m, the spring is not stretched or compressed, and the 10 kg block, which is subjected to a force of 100 N, has a speed of 5 m/s down the smooth plane. Find: The distance s when the block stops.

Dynamics. A dynamics analysis is what allows one to predict the motion of an object or objects, under the influence of different forces, such as gravity or a spring. It can be used to predict the motion of planets in the solar system or the time it takes for a car to brake to a full stop. Nothing that moves can be analyzed without using dynamics

In this problem, you are provided information about the motion of an object (the box moves at constant velocity) and about the forces causing that motion (the pull by the spring and friction.) Force and motion of a single object are always related through Newton’s Second Law, so this is a force or 2nd Law problem.

Jul 25, 2019 1. A Compression spring fixed on one side to a reference. The spring free length is L. 2. An object of mass (m) attached to the spring. 3. A wall on which the mass (m) will be hitting. Initially, the spring is at position (1) and the mass (m) have no velocity.

We begin be calculating the magnitude of each torque individually. Recall that τ = Fr sinθ.Thus τ 1 = (30)(1)sin 120 = 26.0 N-m and τ 2 = (50)(1)sin 30 = 25 N-m. As we can see from the figure, τ 1 acts counterclockwise while τ 2 acts clockwise. Thus the two torques act in opposite directions, and the net torque is thus 1 N-m in the counterclockwise direction.

Fs is the force exerted by the spring. k is the spring constant. x is the spring displacement from the equilibrium position, where the spring force Fs is zero. The figure below illustrates three cases, where a spring is attached to a (stationary) wall on the left and a moving particle (or body) on the right.

Rotational Dynamics There is a very important concept to understand while studying rotational motion of a body, i.e. a body can have rotational motion even if the total external forces acting on the body add up to zero but if the applied force is zero, there can be no rotation.
