Web29 mrt. 2024 · v_f = v_i + a\Delta t vf = vi +aΔt For a given initial velocity of an object, you can multiply the acceleration due to a force by the time the force is applied and add it to the initial velocity to get the final velocity. The "delta" Δ in front of the ‌ t ‌ means it's a change in time that can be written as ‌ t ‌ f ‌ − t ‌ i. Tips WebThe formula for the kinetic energy of an object is given by K = 1 2 m v → 2. The work done on an object is the change in kinetic energy. The work of each force can be found by …

In classical mechanics, the kinetic energy of a point object (an object so small that its mass can be assumed to exist at one point), or a non-rotating rigid body depends on the mass of the body as well as its speed. The kinetic energy is equal to 1/2 the product of the mass and the square of the speed. In formula form: where is the mass and is the speed (magnitude of the velocity) of the body. In SI units, mass is m… touchaheart.co.uk
