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. Which characteristic best describes the effect of a force that causes an object to speed up, slow down, or change direction?
3. What is the primary effect of force on an object?
Force — definition?
An external influence that pushes or pulls objects.
Elastic vs plastic deformation?
Elastic is temporary; plastic is permanent shape change.
Force — definition?
Push or pull acting on an object.
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.
