What does the slope of velocity time graph represent?
The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.
Can you draw a graph for uniform motion?
Distance-Time Graph for Uniform Motion Let’s draw a graph for uniform motion. It is because the slope of a distance-time graph determines the speed of that body, so steeper the slope greater will be the speed of the body.
What is the slope of the displacement time graph when the body has uniform motion?
Displacement-time graph of a body moving with uniform velocity is always a straight line with slope =0.
What is the formula of uniform speed?
Average speed: Average speed is defined as the uniform speed which is given by the ratio of total distance travelled by an object to the total time taken by the object.
What are the characteristics of uniform motion?
Comparison table Between these two types of motions:
| Comparison Parameters | Uniform Motion |
|---|---|
| Average Speed | The motion is similar to the actual speed of the object. |
| Rectilinear Motion | It has zero acceleration. |
| Graph | Distance-time graph shows a straight line |
| Distance | Covers equal distances in equal time interval. |
What is a uniform motion problem?
When they’re at the same spot on the highway, they’ll have both traveled the same distance. We can recognize this is a uniform motion problem. We can use the formula D = R T D=RT D=RT where D is the distance each of them traveled, R is the rate at which they traveled, and T is the time it took them to get there.
What is the formula of non uniform motion?
In non- uniform circular motion, the size of the velocity vector (speed) changes, denoting change in the magnitude of velocity. In either case, the angular velocity in non-uniform circular motion is not constant, as ω=vr ω = v r , and v varies.
What is a good strategy for solving uniform motion problems?

What remains constant in uniform circular motion answer?
Answer: (2) speed When a body is in uniform circular motion, its speed remains constant but its velocity, angular acceleration, angular velocity changes due to change in its direction.
What kind of force is necessary for circular motion?
For objects in uniform circular motion, the net force and subsequent acceleration is directed inwards. Circular motion requires a net inward or “centripetal” force. Without a net centripetal force, an object cannot travel in circular motion.
Does a centripetal force cause circular motion?
It would move in a line away from the circle’s center. It would move in a line tangent to the circular path. A centripetal force causes circular motion because it accelerates an object. toward the center of a circle, which changes the direction of motion but not the speed.
Why does centripetal force cause circular motion?
Centripetal forces cause centripetal accelerations. In the special case of the Earth’s circular motion around the Sun – or any satellite’s circular motion around any celestial body – the centripetal force causing the motion is the result of the gravitational attraction between them.
