Answer:
Three effects of force are:
1) Change in motion: One of the primary effects of a force is that it can cause a change in the motion of an object. A force can either accelerate or decelerate an object, change its direction, or bring it to a complete stop.
2) Deformation: Force can cause deformation in objects, particularly in materials that are not rigid. When a force is applied to an object, it can cause the object to bend, stretch, compress, or twist, leading to a change in its shape or size.
3) Stress and Strain: Force applied to an object can induce stress and strain. Stress refers to the internal resistance or force per unit area within a material, while strain represents the deformation or elongation of an object due to applied forces. Excessive or prolonged forces can lead to structural damage or failure of the object.
These are three effects of force, and there could be additional effects depending on the specific context and situation.
