Q:

What is the difference between static and dynamic loads?

A:

Static loads are loads that exert a constant amount of force, while dynamic loads exert varying amounts of force upon the structure that is upholding them. A simple example of a static load is the weight of a bridge span upon the bridge pilings holding it aloft. A truck moving across that same bridge span would be exerting a dynamic load on the pilings.

Other examples of dynamic loads include wind blowing on the face of a building, water sloshing in a jar and dice bouncing up and out of a can. The variations of dynamic loads can be due to changes in mass, direction of movement, pressure or speed of movement.

• A:

Speed and velocity share many similarities, speed is a scalar property while velocity is a vector property. A vector is a scalar quantity with a direction attached to it.

• A:

Speed measures how fast an object is moving, whereas acceleration is how much the speed of an object changes during a specified period of time. If an object is speeding up, it has a positive acceleration, whereas an object slowing down has a negative acceleration.

• A:

Acceleration refers to the change in velocity of a moving object within a certain period of time, either to a slower or faster pace, while deceleration exclusively refers to the negative acceleration (or slowing down) of an object. In layman's terms, acceleration usually only refers to positive acceleration.
