How do you describe the motion of an object on a graph?
If an object moves along a straight line, the distance travelled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.
How do you describe the motion of an object quizlet?
The description of the distance and direction to the object also must be changed. How can you tell whether or not an object is in motion? Compare its position to that of a reference point. If the distance or direction to the reference point changes, it is in motion.
How will you describe the motion of an objects and its velocity?
To summarize, an object moving in uniform circular motion is moving around the perimeter of the circle with a constant speed. While the speed of the object is constant, its velocity is changing. Velocity, being a vector, has a constant magnitude but a changing direction.
What are five ways motion can be described?
What are five ways motion can be characterized? They can be characterized by position (location of an object), displacement (distance an object has moved), speed (the time rate displacement or object movement), velocity (the direction of the speed), and acceleration (rate of velocity change).
What are the types of motion graphs?
Ans: There are two main types of graphs in motion, namely displacement-time graph and velocity-time graph.
What two things do you need to know to describe the motion of an object?
You can describe the motion of an object by its position, speed, direction, and acceleration. An object is moving if its position relative to a fixed point is changing. Even things that appear to be at rest move.
What happens to friction when two objects?
For instance, when two objects rub together, friction causes some of the energy of motion to be converted into heat. This is why rubbing two sticks together will eventually produce a fire. That’s why lubricants, or liquids, are often used to reduce the friction — and wear and tear — between moving parts.
