A man is driving a car at a constant speed. What is the state of the man w.r.t. a person sitting inside the car?

A man is driving a car at a constant speed. What is the state of the man w.r.t. a tree on the road?

Pick the odd one out.

In a bowling game, what type of motion does the ball perform in the lane? What type of motion do the pins perform when hit by the ball?

Taking the traffic pole as a reference point, Sam observed the state of the passenger inside the yellow bus. He found that the passenger was in motion w.r.t. the traffic pole. What is the frame of reference in which this observation is made?

Which of the following motions repeat themselves after equal intervals of time?

1. The motion of the Moon around the Earth
2. The motion of the hour hand of a clock
3. The motion of a tennis ball during a match
4. The motion of a seesaw when children are playing

the motion of the moon around the earth and the motion of the hour hand of the clock is a periodic motion hence, they repeat themselves after equal intervals of time.

An object moves in such a way that it always stays at a fixed distance from a fixed point. Identify the type of motion of the body

Pick the odd one out.

Which of the following is not an example of rectilinear motion?

Peter collects objects which perform a periodic motion as part of project work. He has already included a pendulum, the guitar, and a toy swing in his collection. Should he also include a wristwatch? Give reasons

Samuel decides to find the average speed of his parent’s car while they take a drive to a park 21 km away from their home. Which of the following would yield him the most accurate result?
a. Look for milestones throughout the journey and note down the distance traveled against the respective time stamps. Later use the formula, average speed = total distance traveled / total time taken to calculate the average speed.
b. Keep an eye on the odometer and note down the distance traveled by car against the respective time stamps. Later use the formula, average speed = total distance traveled / total time taken to calculate the average speed.
c. Keep an eye on the speedometer and note down the speed at different locations. Later use the formula average speed = sum of all the speeds/ no. of observations to calculate the average

Observe the picture below. Can we consider the position of the child as a reference point to study the state of a person sitting inside the car? Give reasons

Which of the following is true about the distance traveled by a moving object?
a. It always increases with time
b. It can be zero
c. Generally, it is greater than the displacement
d. It can also be equal to the displacement at times

In which of the following cases is the displacement equal to the distance traveled by the body?
