Force is an invisible quantity characterized by pulling and pushing actions, whose effects on objects reveal its presence and magnitude.
Dynamic change : a change in an object's motion resulting from a force, which can manifest as acceleration, deceleration, or a change in direction.
Elastic deformation : a temporary change in an object's shape caused by a force, which reverts to the original form once the force is removed.
Plastic deformation : a permanent change in an object's shape due to a force, which remains after the force is no longer applied.
1. Which characteristic correctly distinguishes tensile force from compressive force?
2. What is the primary effect of force on an object?
3. Which characteristic best describes the effect of a force that causes an object to speed up, slow down, or change direction?
Force — definition?
An external influence that pushes or pulls objects.
Force — definition?
Push or pull acting on an object.
Elastic vs plastic deformation?
Elastic is temporary; plastic is permanent shape change.
Tensile vs compressive force — difference?
Pulling versus pushing actions.
Force effects — types?
Motion change and shape deformation.
Elastic deformation — description?
Temporary shape change, reverts after force removed.
