E1 quiz JEE ADV

From the following, identify the first equation of motion.

• s = vt - 1/2at^2
• v^2 = u^2 + 2as
• v = u + at
• s = ut + 1/2at^2

If a particle is moving with uniform velocity along the straight line, then its acceleration is_____

• decreasing
• zero
• constant
• increasing

Choose the correct equation

• v - u = at

• u = v + at

• a = v + at

• t = v + ua

The first equation of motion gives the relation between

• displacement - velocity

• initial velocity and final position
• time and final acceleration
• velocity - time

The rate of change of motion in a specified direction is called ______

• force
• momentum
• velocity
• acceleration

When a particle is moving with uniform acceleration, then

• Path is straight line?

• The direction of average acceleration and direction of instantaneous acceleration will coincide

• Path may be straight line

• None of these

Choose the correct options

• A body having long zero acceleration can have constant velocity

• Displacement is the rate of change of velocity

• A body having zero acceleration can have constant velocity

• Acceleration is the rate of change of velocity

A body has an acceleration of -3 m/s^2, Then It’s retardation is ____

• 3 m/s^2
• 6 m/s^2
• 0 m/s^2
• -3 m/s^2

• 50 m/s
• 65 m/s
• 30 m/s
• 75 m/s

Given that S = 2t - 1/2 x 5t^2 using this equation, find its acceleration
