State the type of motion represented by the following sketches in Figures.
Give an example of each type of motion.
From the diagram given below, calculate acceleration.
A motorbike, initially at rest, picks up a velocity of 72 kmh−1 over a distance of 40 m. Calculate
- acceleration
- time in which it picks up above velocity.
A motor bike running at 90 kmh−1 is slowed down to 18 kmh−1 in 2.5 s. Calculate
- acceleration
- distance covered during slow down.
Out of energy and acceleration, which one is a vector?
Assertion: The accelerated motion of an object may be due to change in magnitude of velocity or direction or both of them.
Reason: Acceleration can be produced only by change in magnitude of the velocity. It does not depend the direction.
If the velocity of a body does not change, then its acceleration is ______.
m/s2 is the unit of ______.
A car is being driven at a speed of 20ms-1 when brakes are applied to bring it to rest in 5 s. The deceleration produced in this case will be ______.
An object can be moving with uniform speed but with variable acceleration.
