## True and False

a) If the object is moving with large velocity, its acceleration is high

b) If the particle is speeding up, acceleration and velocity both could in negative direction

c) If the particle is slowing down, the acceleration and velocity are in opposite direction

d) When the particle moves with constant velocity, the instantaneous speed is equal to average speed

e) The speedometer of the car shows the average speed of the car

f) The car is turning on the curve and speedometer tells the speed at 40 km/hr, then the car is moving with constant velocity

g) An object can accelerate with-out changing the speed

h) A particle can accelerate if the velocity is constant

i) The car can accelerate if its speed slows or brought up or when it changes its direction.

j) As the body freely falls due to acceleration due to gravity in vacuum, it covers equal distance in equal time.

k) When a ball is thrown up, acceleration and velocity are zero at the top point
