An object comes to rest. It means that ___.

A body is accelerating negatively. Its _____.

In this case, the velocity is decreasing and hence, the body is negatively accelerating.

A vehicle’s velocity increases by 5 m/s every second. What does it mean?

Acceleration can be defined as the rate of change of velocity of an object with respect to time and in this case, the vehicle is also accelerating with a unform change in velocity.

An object starts from rest. It means that _____.

Rest implies that the body was stationary with respect to the ground. Any body which doesn't move has zero velocity, since it doesn't covers any distance. Thus, any body starting from rest has initial velocity= zero.

A body is positively accelerating. Its ____

If an object travels in a straight line and it's velocity increases or decreases by equal amounts in equal intervals of time, then the acceleration of the object is said to be uniform.

The displacement of a body = _____.

Which of the following is called the position-time relation?

s = ut + ½ at² is position-time relation as it has both the components of position and time.

A car travels 2 m in a second. What is the speed of the car?

An object’s velocity increases by equal amounts in equal intervals of time. It is in _____.

In uniformly accelerated motion the object's velocity increases by equal amounts at equal intervals of time.

Mira plotted a s-t graph of her car journey by collecting data during a drive. She started from rest and slowly increased her velocity until it reached a particular value. Then she maintained a uniform motion. Lastly, she slowed down gradually to bring the car to a stop. Which of the following graphs would resemble the graph plotted by Mira?

 

The s-t graph of a car is shown in the figure below. Choose the option that shows the right ascending order of the magnitudes of velocities that the car had throughout its motion.

The slope of the s-t graph of a ball dropped from the top of a building ____ as we move towards the right.

The s-t graph of a car is shown in the figure below. In which of the sections was the car slowest

The total distance covered by the body whose s-t graph is shown below is ____m.

The s-t graph of a person’s journey is shown in the figure below. Calculate the highest magnitude of velocity of the person.

The s-t graph of a person’s journey is shown in the figure below. Identify the section in which the person was moving at the fastest pace.
