What is meant by accelerated motion?
A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing. For all other kinds of motion, both effects contribute to the acceleration.
What is accelerated motion with example?
Some uniform accelerated motion examples include a ball rolling down a slope, a skydiver jumping out of a plane, a ball dropped from the top of a ladder and a bicycle whose brakes have been engaged.
Why is it called accelerated motion?
In a circular motion, there is a continuous change in the direction of motion. The velocity changes when the direction changes. Therefore, circular motion is an accelerated motion.
What type of motion is accelerated motion?
In general, a uniformly accelerated motion is the one in which the acceleration of the particle throughout the motion is uniform….Uniformly accelerated motion in a plane:

Is acceleration possible in uniform motion?
An object undergoing uniform circular motion does not accelerate.
Which of the following is accelerated motion?
Velocity is often thought of as an object’s speed with a direction. Thus, objects which are accelerating are either speeding up, slowing down or changing directions. Changing the velocity in any one of these three ways would be an example of an accelerated motion.
What’s the difference between speed and velocity?
Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.
What is the preferred SI unit for acceleration?
meter per second squared
What force is responsible for acceleration?
Newton’s second law states that a net force on an object is responsible for its acceleration. If air resistance is negligible, the net force on a falling object is the gravitational force, commonly called its weight w.
Does force change motion?
A force can change the direction in which an object is moving. A bigger force on an object will produce a bigger change in the motion. A heavier object requires a larger force than a lighter object in order to undergo the same change in motion.
Why does force cause acceleration?
An unbalanced force acting on an object causes it to accelerate. The bigger the unbalanced force acting on the object the bigger the acceleration of the object. The more mass the object has, the more inclined it is to resist any change to its motion.
Does force cause acceleration?
Newton’s second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.
How does force affect motion?
Forces affect how objects move. They may cause motion; they may also slow, stop, or change the direction of motion of an object that is already moving. Since force cause changes in the speed or direction of an object, we can say that forces cause changes in velocity. So forces cause acceleration.
What are 5 ways force can change motion?
What are five ways a force can change motion? Answer: The action by a force can cause an object to move or speed up , to slow down , to stop, or to change direction.
What are the two factors affecting motion?
Objects change their motion because unbalanced forces act on them. There are four main factors that affect the motion of objects. These factors are force, friction, inertia, and momentum.
What factor makes objects move faster?
LAW 2 – Forces make things speed up (or accelerate). When a force pushes or pulls the object, the object will move in the direction of the force. The bigger the force, and the lighter the object, the greater the acceleration.
What factors affect GPE?
Gravitational Potential Energy is determined by three factors: mass, gravity, and height. All three factors are directly proportional to energy.
