The linear motion, also called the Rectilinear Motion can be of two types: Uniform linear motion with constant velocity or zero acceleration.
How do you solve a question of motion in a straight line?
- The first point to be careful is to find out the given data in the question.
- The second important point is to find out what are the quantities that are required to be determined.
- Now we need to use the appropriate equations to obtain the required parameter and conclude the solution.
What are the important topics in motion in a straight line?
Motion in a Straight Line: Acceleration, Velocity, Displacement and Speed.
Which chapter is motion in straight line Class 11?
Motion is one of the significant topics in physics.
What is the formula for displacement?
Displacement = Final position – initial position = change in position.
What is law of straight line?
Newton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
What is the SI unit of speed?
The SI unit of speed is given in terms of basic units of distance and time. Thus, the SI unit of speed is metre per second or m/s.
What are the 3 equation of motion?
The three equations are, v = u + at. v² = u² + 2as. s = ut + ½at²
What are types of speed?
- Uniform speed.
- Variable speed.
- Average speed.
- Instantaneous speed.
Is kinematics important for NEET?
Kinematics is the sector of mechanics that defines the motion of points, systems, or objects. The Kinematics in NEET is approximately 3 to 4% and students can also imagine direct questions from the section which makes it one of the best scoring topics.
Is kinematics important for JEE?
Kinematics is an important topic for JEE exams. It mainly consists of one-dimensional and two-dimensional motion, and the questions asked in the examination are based on their applications.
Is motion in a straight line important for NEET?
Important notes of Physics for NEET, JEE for Motion in a Straight line are useful for all aspirants preparing for entrance exams including JEE, NEET. Important notes are also helpful for revision when you have less time and have to study many topics.
What formula is V u at?
u = Initial velocity. v = Final velocity. a = Acceleration. t = Time of motion.
What is speed with direction?
The speed of an object in a particular direction is called the velocity of an object.
What is SI unit displacement?
The standard unit of displacement in the International System of Units (SI) is the meter (m). Displacement is usually measured or defined along a straight line. For example, we might speak of the distance between the center of the earth and an orbiting satellite , and measure it as 13,000,000 meters.
Can velocity be negative?
Velocity: The velocity of an object is the change in position (displacement) over a time interval. Velocity includes both speed and direction, thus velocity can be either positive or negative while speed can only be positive.
What is the maximum displacement?
Amplitude is the maximum displacement of a particle from its mean position.
What is Newton’s 2nd law called?
The other name for Newton’s second law is the law of force and acceleration.
What is the unit of force?
The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg. The second, unit of time — symbol s.
What is Newton’s first law called?
Newton’s First Law: Inertia Newton’s first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
What are the 7 basic units?
- Length – meter (m)
- Time – second (s)
- Amount of substance – mole (mole)
- Electric current – ampere (A)
- Temperature – kelvin (K)
- Luminous intensity – candela (cd)
- Mass – kilogram (kg)
What is the symbol for speed?
Speed gets the symbol v (italic) and velocity gets the symbol v (boldface). Average values get a bar over the symbol. Displacement is measured along the shortest path between two points and its magnitude is always less than or equal to the distance.
What is final velocity?
Initial and Final Velocity On the other hand, the final velocity is a vector quantity that measures the speed and direction of a moving body after it has reached its maximum acceleration.
What is called uniform circular motion?
What is Uniform Circular Motion? The movement of a body following a circular path is called a circular motion. Now, the motion of a body moving with constant speed along a circular path is called Uniform Circular Motion.
What is initial velocity?
Initial Velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts. They are four initial velocity formulas: (1) If time, acceleration and final velocity are provided, the initial velocity is articulated as. u = v – at.
