Types of forces:

the downward force on an object from the pull of ______, otherwise known as 'weight' is equal to the objects mass time acceleration due to the force of ________

(a)  

Types of forces:

The property of an object that causes it to resist changes to its state of motion by an application of force. A stationary object will tend to resist being moved, and a moving object will resist change in its speed or direction of movement.

(a)  

Types of forces:

The resistive force encountered when we attempt to move two objects in contact with each other. The greater the (a)   al force, the more difficult it is to move.

Types of forces:

The resistive force encountered by an object moving through a ______ is called _______ _______, this becomes a significant factor when we attempt to move either a volume of water or in a body of water.

(a)  

Types of forces:

The main characteristic of _______ is that the greater the _______ component (spring or band) is stretched, the greater the resistance becomes. The property of _______ of an object is its tendency to return to its original length or shape.

(a)  

Types of forces:

(a)   force pushes in on the ends of an object and tries to make the object shorter. A good example is the weight of the bar resting on a lifter's back at the top of a low bar back squat.

Types of forces:

(a)   force pulls out on the ends of an object and tried to make the object longer. An example would be a lifter's arms in tension during a conventional deadlift.

(a)   forces occur when one vertebrae is sliding forward or backward on the vertebrae below it.

Types of forces:

Occurs when two forces of a similar strength are applied on either end of the object in the opposite directions. This causes twisting of one end which is sometimes referred to as a twisting force.

(a)  

Types of forces:

The internal reaction happening in a structural element when an external force or moment, which can cause the element to bend. An example of this would be the bending force on the torso during a prone plank / bridge
