## How do you calculate VF2?

Final velocity (v) squared equals initial velocity (u) squared plus two times acceleration (a) times displacement (s). Solving for v, final velocity (v) equals the square root of initial velocity (u) squared plus two times acceleration (a) times displacement (s).

## What does VF2 mean in physics?

About this tutor › This is one of the standard kinematic equations used in physics to track the motion of an object, neglecting friction. In this equation we have vf (final velocity), vi (initial velocity), a (acceleration), xf (final position) and xi (initial position).

**What does VF 2 mean?**

It reads: The square of the final velocity minus the square of the original velocity equals twice the acceleration times the displacement. An object accelerates at 2.0 m/s/s changing its velocity from 4.0 m/s to 6.0 m/s.

### How do you use vu?

v=u+at is the first equation of motion. In this v=u+at equation, u is initial velocity. v is the final velocity.

### What does YF mean in physics?

where xi yi and xf yf are initial and final positions, vi and vf are initial and. final speeds, and t is time (t. i. = 0). Vertical: Motion with constant acceleration.

**What does XO mean in physics?**

Xo. position along x axis at time 0; initial position. X. position along x axis (m)

#### What is 1st equation of motion?

The first equation of motion is v = u +at. Here, v is the final velocity, u is the initial velocity, a is the acceleration and t is the time. The velocity-time relation gives the first equation of motion and can be used to find acceleration.

#### Is velocity a speed?

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. For example, 50 km/hr (31 mph) describes the speed at which a car is traveling along a road, while 50 km/hr west describes the velocity at which it is traveling.

**What is the formula D 1 2at 2?**

Let’s start out by saying what this equation is. is an equation that states that if an object has a constant acceleration, the distance it travels away from where it began will equal half the acceleration times time squared plus the initial velocity times time.
