A particle with positive acceleration is slwing down if its ……………………………………is negative.

Assertion :- A particle has positive acceleration it means that its speed always increases. Reason :- Acceleration is the rate of change of speed with respect to time.

Assertion :- A particle has positive acceleration it means that its speed always increases. Reason :- Acceleration is the rate of change of speed with respect to time.

Assertion :- A particle has positive acceleration it means that its speed always increases. Reason :- Acceleration is the rate of change of speed with respect to time.

Assertion : In the s-t graph as shown in figure, velocity of particle is negative and acceleration is positive. Reason : Slope of s-t graph is negative and increasing in magnitude.

Assertion : In the s-t graph as shown in figure, velocity of particle is negative and acceleration is positive. Reason : Slope of s-t graph is negative and increasing in magnitude.

For a particle moving along straight line with constant acceleration (a), we define velocity of the particle with time as v=u+at , (u = initial velocity) Draw the velocity-time graph of the particle in following situations. (i) Velocity is decresing with time (i.e., acceleration in negative) (ii) Initial velocity is negative but acceleration is positive

A particle is moving along x-direction with a constant acceleration a. The particle starts from x=x_0 position with initial velocity u. We can define the position of the particle with time by the relation x=x_0+ut+(1)/(2)at^2 plot the position of the particle in relation with time is following situations (i) If initial position of the particle is on negativ x-axis, initial velocity is positive and acceleration is negative. (ii) If initial position is positive, initial velocity is negative and acceleration is positive.
