What else can I help you with?
What is horizontal acceleration?
It is acceleration in the horizontal direction. This would happen as a result of a net horizontal force acting on a body.
What are the horizontal components of accelaration of a body when thrown horizontally with unifornm speed?
When a body is thrown horizontally with uniform speed, there is no change in the horizontal velocity, so the horizontal component of acceleration is zero. The only acceleration acting on the body is due to gravity in the vertical direction.
Can a body move horizontally with acceleration in vertical direction If yes why?
Yes, a body can move horizontally with acceleration in the vertical direction if it is subject to a force that is acting at an angle. This can cause the body to experience motion in both the horizontal and vertical directions simultaneously, resulting in acceleration in the vertical direction while still moving horizontally.
Derive an expression for acceleration of a body moving downward on an inclined plane making angle 0 with the horizontal when friction is present?
The acceleration of a body moving downward on an inclined plane with angle θ when friction is present can be expressed as: a = g(sinθ - μcosθ) where: a = acceleration of the body g = acceleration due to gravity θ = angle of the inclined plane μ = coefficient of friction
A horizontal force acts a body that is free to move can it produce an acceleration if the force is less then the weight of that body?
Yes it can, and if less force is needed if you eliminate the possibility of friction. You can find many examples of this, but i think this is an excellent opportunity to devise an experiment and practice your scientific methods.
On a speed time graph a horizontal line shows the change in speed is?
A horizontal line parallel to speed axis indicates that the body is moving at a constant speed i.e. it's speed doesn't change with passage of time. The body may have zero or non zero acceleration, but it will always have non zero velocity. But, that doesn't mean that body's velocity is constant and it is not accelerated. For example in uniform circular motion the speed of body remains constant but velocity changes due to change in the direction of motion. Also there is acceleration towards center of circle called centripetal acceleration which changes the direction of velocity. For this acceleration a force should act towards the center called centripetal force. If speed is constant then the force, if present, must act in direction perpendicular to the immediate direction of motion i.e. perpendicular to the tangent drawn at any point on the path of motion.
If a body is acted by a constant force the body will have uniform?
"acceleration"
When a body has velocity no constant has acceleration or no?
Yes. If a body has a constant velocity there is no acceleration, but if the velocity is changing there is acceleration present.
What is the acceleration of mass?
force acting on unit mass of body is the acceleration of that body.
When a body has constnat velocity what is the acceleration?
When a body has constant velocity, the acceleration is zero. This is because acceleration is the rate at which velocity changes, so if velocity is constant, there is no change and hence no acceleration.
Can a body have an acceleration when it is momentarily at rest?
No, a body cannot have acceleration when it is momentarily at rest. Acceleration is the rate of change of velocity over time, so if the body is at rest, its velocity is zero, and therefore its acceleration is zero as well.
How can you recognise body getting into acceleration?
a body is accelerating if it is speeding up faster and faster. Acceleration is the change in velocity. or the change in speed. Slowing down is also acceleration but it is negative acceleration or de acceleration.
