# Dynamics

## Motion of bodies and the action of forces in producing or changing their motion - velocity and acceleration, forces and torque.

### Acceleration

Change in velocity vs. time used.

### Acceleration of Gravity and Newton's Second Law

Acceleration of gravity and Newton's Second Law - SI and Imperial units.

### Acceleration Units Converter

Converting between units of acceleration.

### Acceleration vs. Velocity Equations

Useful equations related to acceleration, average velocity, final velocity and distance traveled.

### Angular Motion - Power and Torque

Angular velocity and acceleration vs. power and torque.

### Average Velocity

Distance traveled vs. time used.

### Formulas of Motion - Linear and Circular

Linear and angular (rotation) acceleration, velocity, speed and distance.

### Impact Force

Impact forces acting on falling objects hitting the ground, cars crashing and similar cases.

### Impulse and Impulse Force

Forces acting a very short time are called impulse forces.

### Kinetic Energy

Energy possessed by an object's motion is kinetic energy.
