Which is true about an unbalanced force on an object?

T or F: An unbalanced force on a body will always impact the objet’s speed. True T or F: The reason why initially moving objects tend to come to rest in our “everyday” life is because they are being acted on by unbalanced forces. False T or F: An unbalanced force on an object will always change the object’s direction. True

How are objects in motion affected by Newton’s first law?

a measure of the gravitational force exerted on an object; its value can change with the location of the object in the universe Newton’s First Law An object at rest remains at rest, and an object in motion continues in motion with constant velocity (that is,constant speed in a straight line) unless the object experiences a net external force.

What causes an object to come to a rest position?

T or F: An object’s inertia causes it to come to a rest position. T or F: When an object is stationary, all of the forces acting on it are balanced. T or F: The only way to slow down a moving object is to apply a net force to it.

When does an object have no net forces?

T or F: An object that is not accelerating or decelerating has no net forces acting on it. T or F: An object’s inertia causes it to come to a rest position. T or F: When an object is stationary, all of the forces acting on it are balanced.

How to define a two-force rigid body?

A two-force body can be more generally defined as a rigid body subjected to forces acting at only…. a rigid body subjected to forces acting at only three points is called a… Consider a rigid body subjected to s system of forces which can be reduced to three forces acting at three points.

What are two important concepts associated with the effect of a force?

Two important concepts associated with the effect of a force on a rigid body are… The combination of two forces which have the same magnitude, parallel lines of action, and opposite sense…

What’s the name of the force couple system?

This particular force-couple system is called a _______ b/c the resulting combination of push and twist. A wrench consists of two _______ vectors, a force R and a couple vector. Whe the force and the couple are both equal to zero the external forces form a system equivalent to zero, and the rigid body is said to be in…..

When do two forces have the same effect?

Forces holding the component parts together. Two forces are said to be ________ (have the same effect on a rigid body) if they have the same magnitude, direction and same LOA. The principle of transmissibility should be avoided or used with care, in determining….
