What are the four equations of linear motion?
Equations of Motion
| Variable | Equation |
|---|---|
| Velocity | v, equals, u, plus, a, t,v=u+at |
| Displacement with positive acceleration | s, equals, u, t, plus, one half, a, t, squared,s=ut+21at2 |
| Displacement with negative acceleration | s, equals, v, t, minus, one half, a, t, squared,s=vt−21at2 |
What are the quantities of linear motion?
Linear motion is motion in a straight line. This type of motion has several familiar vector quantities associated with it, including linear velocity and momentum. These vector quantities each have a magnitude (a scalar, or number) and direction associated with them. Similarly, circular motion is motion in a circle.
What are the physical quantities that relate equation of motion?
The three equations of motion are known as kinematic equations. Quantities associated with these kinematics equations are – displacement (and distance), velocity (and speed), acceleration, and time.
How many types of linear equations are there in motion?
Linear motion can be in 2 types 1) Rectilinear motion 2) Curvilinear motion.
What are the four equations of motion at constant acceleration?
v – = x − x 0 t . v – = v 0 + v 2 . v – = v 0 + v 2 . The equation v – = v 0 + v 2 v – = v 0 + v 2 reflects the fact that when acceleration is constant, v – is just the simple average of the initial and final velocities.
Which physical quantity in linear motion is analogous?
Moment of inertia
Moment of inertia in rotational motion is an analogue of a physical quantity in linear motion.
What is the equation of linear motion?
As we use the equation of motion F=ma to describe a linear motion, we can use its counterpart τ=dLdt=r×F τ = d L dt = r × F , to describe angular motion.
What are the four equations for free falling motion?
Imagine an object body is falling freely for time t seconds, with final velocity v, from a height h, due to gravity g. It will follow the following equations of motion as: h= \frac{1}{2}gt^2. v²= 2gh….The formula for free fall:
| h | Height traveled |
|---|---|
| t | Time taken |
What are the types of linear motion?
The two types of linear motion are uniform motion and non-uniform motion and three types of rectilinear motion are uniform rectilinear motion, uniformly accelerated rectilinear motion, and rectilinear movement with non-uniform acceleration.
Which physical quantity in rotational motion is analogous of force in linear motion?
Answer: The physical quantity which is the rotational analogue of force is Torque.. It’s SI unit is Newton metre (N m)…. Relation between angular momentum and torque is same as between the linear momentum and force.
How are physical quantities used in linear motion?
Physical Quantities in Linear Motion. Our goal in this section, is to derive the equations that can be used to describe the motion of an object in terms of its three kinematic variables: velocity, displacement, and time. There are three ways to pair them up: velocity-time, displacement-time, and velocity-displacement.
How to choose the correct kinematic equation for linear motion?
Kinematic Equations for Linear Motion (For constant acceleration ONLY) ** To select the appropriate equation to solve a particular problem: 1) List what quantities are given – (will be 3) 2) List what is being asked for – (will be 1). 3) Find the equation in the table that contains all 4 involved quantities.
Why are kinematic equations so important in physics?
Kinematic equations form the very foundation of any question you intend to solve in physics. Be it uniform rectilinear motion or rotational motion, these equations will always help you to find the correct answer.
