What is a moving object?
1. An entity (data element) in space with a varying position in the course of time. At any specific time instance, a moving object is characterized by its position, its direction of movement, and its speed of movement.
Is zero velocity possible?
Yes, an object can have zero velocity and still be accelerating simultaneously.
Is it possible for an object to move in a certain direction with an acceleration in the perpendicular direction?
Explanation: An object is a moving in a certain direction with an acceleration in the perpendicular direction. The above condition is possible. Example of such a situation in real life would be when a stone tied to a string is whirled in a circular path.
What is required to specify the position of an object?
What is required to specify the position of an object? To specify the position of an object, a reference point called origin is required. 5. … The total distance traversed by an object is called path length.
What are the 5 ways an object can move?
Question: 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.
Does 0 velocity mean 0 acceleration?
Yes indeed. Derivative of velocity with respect to time is acceleration. That means if accelerations is zero, velocity must be constant. … Also if the velocity is 0(which is itself a constant) also indicates that acceleration is zero.
Can an object have 0 velocity and still be accelerating?
– J. Yes, it’s possible to have zero speed while accelerating, but only for an instant. … Acceleration is the rate at which an object’s speed and direction are changing with time, so whenever an object passes through zero speed as it reverses directions it has a non-zero acceleration but a speed of zero.
Can the speed of body be negative?
Speed = Distance travelled/Time taken
The ratio of distance travelled and the time taken by a body can be zero but not negative. Since distance and time are positive quantities and speed is obtained by the ratio of these two quantities, speed cannot be negative.
What is an example of uniform acceleration?
In simpler terms, a number equal to the acceleration in such a motion does not change as a function of time. 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.
Is it possible an object moving with an acceleration but with uniform speed?
Answer: Circular motion is an example of an object which is moving with acceleration but with uniform speed. … In case of circular motion, the velocity keeps changing as direction changes( though magnitude remains constant) and hence the object is accelerated but there’s no change in speed( the magnitude).
Which of the following situations is possible an object can have acceleration but constant velocity?
An object can have acceleration, but constant velocity. The velocity of an object may be zero but acceleration is not zero. Distance and the magnitude of displacement are equal in circular motion. Average speed and the magnitude of average velocity are always equal in circular motion.
What does the path of an object look like when it is in uniform motion?
In uniform motion, the object moves along a straight path i.e. the path of object is a straight line.
Can a body move horizontally with acceleration in vertical direction?
Yes, Its possible. A body projected at some angle will have horizontal motion, while Acceleration due to gravity “g” will be acting vertically down. … When a body tied with rope moves in a vertical circular path, at the bottom most point velocity is horizontal and acceleration is in the vertical direction.
What is the acceleration of an object that moves at a uniform speed and direction Why?
An object which experiences either a change in the magnitude or the direction of the velocity vector can be said to be accelerating. This explains why an object moving in a circle at constant speed can be said to accelerate – the direction of the velocity changes. 3.
What is the position time graph?
The shapes of the position versus time graphs for these two basic types of motion – constant velocity motion and accelerated motion (i.e., changing velocity) – reveal an important principle. The principle is that the slope of the line on a position-time graph reveals useful information about the velocity of the object.
What are the two types of motions?
There are different types of motion: translational, rotational, periodic, and non periodic motion. A type of motion in which all parts of an object move the same distance in a given time is called translational motion.
In which type of motion is instantaneous and average velocities equal?
Instantaneous velocity can be equal to average velocity when the acceleration is zero or velocity is constant because in this condition all the instantaneous velocities will be equal to each other and also equal to the average velocity.
How can we make an object move?
Force can make things move, change shape or change their speed. Some forces are direct and happen when two things touch (like a foot kicking a ball) or over a distance (such as a magnet or gravity). Friction is the force between two objects in contact with each other that will resist an attempt to move them.
How does a force change the position of an object?
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 do objects move in different ways?
2.2. 2.1. 2 Demonstrate that objects move in a variety of ways, including a straight line, a curve, a circle, back and forth, and at different speeds. 2.2 The motion of an object can be changed by push or pull forces.
