The shape, the slope, and the location of the line reveals information about how fast the object is moving and in what direction; whether it is speeding up, slowing down or moving with a constant speed; and the actually speed and acceleration value that it any given time.
“In physics, a physical body or physical object (sometimes simply called a body or object) is a collection of masses, taken to be one. For example, a football can be considered an object but the ball also consists of many particles (pieces of matter).” - Wiki
Aug 17, 2022 · The effects of forces. Friction. Changing shapes. Temporary changes of shape. Springs and wires. In this section, we will learn how different objects and their size affect the impact of the forces applied to them. Forces are pushes/pulls of one thing onto another. An example of a force is gravity.
In natural language and physical science, a physical object or material object (or simply an object or body) is a contiguous collection of matter, within a defined boundary (or surface), that exists in space and time. Usually contrasted with abstract objects and mental objects. [1][2]
Aug 17, 2020 · For example, bridges must be able to hold up the materials that make the bridge, as well as all of the traffic travelling across it. One of the shapes that can bear weight very well is the triangle. But what makes triangles so good at this? Let’s look at how a triangle transfers a force.
Jan 30, 2021 · Here are some examples of physical properties: Albedo – reflectivity of an object. Area – size of a two-dimensional surface. Boiling point – temperature at which a liquid changes into a gas. Brittleness – tendency to break under stress. Color – wavelengths of light reflected by matter. Density – amount of matter per unit of volume.

Explain the limit where a deformation of material is elastic. Describe the range where materials show plastic behavior. Analyze elasticity and plasticity on a stress-strain diagram. We referred to the proportionality constant between stress and strain as the elastic modulus.
