When a ball bounces up it executes___________ motion.

An apple falling under gravity is an example of:

When a ball is thrown vertically upwards, it attains a height of 19.6 m; find the initial velocity of the ball and the time taken by it to rise to the highest point. (Acceleration due to gravity, g=9.8 m/s²)

Which of the following is not correct?

A stone is released from the top of a building of height 19.6 m then its final velocity just before touching the ground will be: (taking g = 9.8 m/s²)

A ball is thrown vertically upwards. Which of the following graph/graphs represent the velocity-time graph of the ball during its flight (air resistance is neglected)?

Acceleration of a particle changes when:

When an object is thrown upward during upward motion, it executes ___________ motion.

An object is launched upwards and rises to a height of 10 m. Calculate the velocity with which the object was thrown upwards? Take g=9.8 m/s²

The weightlessness of a diver jumping from a height is a situation of (when we neglect the air resistance):

A body of mass of 10 kg is measured using a spring balance which is under freefall then what will be the reading of the spring balance?

During freefall the net force acting on a body is:

We have weight because of _____ force.

Read the statements and mark the correct option.
Statement 1: The acceleration due to the gravity of earth does not depend upon the body's mass.
Statement 2: Acceleration due to gravity remains constant.

If the mass of a body on the moon is 50 kg, what is its weight on the earth?

What is the mass of a body whose weight is 49 newtons?

The correct option is d)5 kg.
The weight of the body = 49 N
Weight of body = mass of body x gravity
49= mass x 9.8
mass = 49/9.8 = 5 Kg
