What is the direction of acceleretion of a body in circular motion?
-- The acceleration is directed from the body to the center of the circle. -- The velocity is tangent to the circle at the place where the body is. That direction is also perpendicular to the acceleration at that moment.
Acceleration takes place when?
Acceleration occurs when there is a change in an object's velocity, either in magnitude or direction. This change can result from an increase or decrease in speed, or a change in the object's path of motion. Acceleration is a vector quantity, meaning it has both magnitude and direction.
What motion mean?
Motion refers to the act of changing position or location. It involves the movement of an object from one place to another. In physics, motion is described in terms of speed, velocity, acceleration, and direction.
What the law of acceleration?
Newton's second law of motion, commonly known as the law of acceleration, states that when a body is acted on by a force, its resulting change in momentum takes place in the direction in which the force is applied, is proportional to the force causing it, and is inversely proportional to its mass. F = ma net force = mass*acceleration
What is a change in the state of motion evidence of?
A change in the state of motion of an object indicates that a force has been applied to it. It accelerates in response, and this appears as a change in its state of motion. It may speed up, slow down, or change direction in response to the applied force.
What is newtons scond law of motion?
Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically, this can be written as: F = ma, where F is the net force, m is the mass of the object, and a is the acceleration.
Explain the second law of motion?
Second law: The acceleration a of a body is parallel and directly proportional to the netforce Facting on the body, is in the direction of the net force, and is inversely proportional to the mass m of the body, i.e., F = ma.
An object moving in a certain direction with an acceleration in the perpendicular direction?
The object is running in circles, literally. Example, take a yo-yo. Unwind the string from the toy. Then find a place where it is safe from hitting anyone else. Start whirling the yo-yo. It goes in circles. You are applying a force to the yo-yo through the string. According to Newton's 2nd law of motion, F = ma. The acceleration is parallel to the force. However, the yo-yo motion is tangential to the force, meaning that anytime the string is cut, the yo-yo will fly off perpendicular to the force at the breaking point.
What are the differences between rotational and translational motion?
Rotational motion involves an object spinning around an axis, while translational motion involves an object moving from one place to another in a straight line. Rotational motion is characterized by angular velocity and acceleration, while translational motion is characterized by linear velocity and acceleration.
When are the displacement velocity and acceleration equal to zero for the motion of a mass on a spring?
Displacement and acceleration are zero at the instant the mass passes through its "rest" position ... the place where it sits motionless when it's not bouncing. Velocity is zero at the extremes of the bounce ... where the expansion and compression of the spring are maximum, and the mass reverses its direction of motion.
When does an unbalanced force take place?
An unbalanced force occurs when the net force acting on an object is not zero, causing a change in the object's motion or position. This can happen when forces are unequal in magnitude or opposite in direction, leading to acceleration or deceleration of the object.
