What is the direction of acceleration of a body when it is thrown upwards and it is momentarily at rest at its highest position?

When body going vertically upwards, reaches at the highest point, then it is momentarily at rest and it then reverses its direction. At the highest point of motion, its velocity is zero but its acceleration is equal to acceleration due to gravity.

When a ball is thrown vertically upward its velocity and acceleration will be?

At highest point velocity of the particle is zero and its acceleration is equal to the acceleration due to gravity acting in the downward direction.

What is the direction of acceleration due to gravity if the body is thrown vertically upward?

Explanation: Sol. If a body is thrown vertically upwards or downwards, the acceleration acting on the body is uniform i.e. acceleration due to gravity = g, in the downward direction.

Is velocity upward or downward?

The diagram depicts an object launched upward with a velocity of 75.7 m/s at an angle of 15 degrees above the horizontal. For such an initial velocity, the object would initially be moving 19.6 m/s, upward and 73.1 m/s, rightward….Projectile Motion Notes.

Time	Horizontal Velocity	Vertical Velocity
5 s	20 m/s, right	49.0 m/s, down

When a ball thrown vertically upward the velocity of a ball is?

The total time it takes to return to the surface of the earth. Hint: When a ball is thrown upwards with a certain velocity, the ball moves against the acceleration due to gravity and attains a maximum height. At the point of maximum height, the velocity of the ball is zero.

When a body is thrown up the acceleration due to gravity?

Explanation: omg Assertion : When a body is thrown up, the acceleration due to gravity at the topmost point is zero. Reason : The acceleration due to gravity is always directed downwards towards the centre of the earth for a freely falling body.

What is the direction of acceleration in vertical motion?

Typically, we define the positive vertical direction as upwards, and the positive horizontal direction is usually the direction of the object’s motion. When this is the case, the vertical acceleration, g, takes a negative value (since it is directed downwards towards the Earth).

What is the maximum velocity when a body is thrown upwards?

For a body thrown upwards, the maximum velocity is at the moment it leaves your hand..after that it won’t have an acceleration upwards. Only acceleration is gravity which is pulling the body downwards..so, the upward velocity decreases by 9.8 m/s every second.

What are the velocity and acceleration when a ball is thrown vertically?

A ball is thrown vertically upward. What are its velocity and acceleration? When a ball is thrown vertically upward, it’s acceleration is -g(-9.8m/s) because it’s motion is in opposite direction to the gravitational attraction on the body, it’s velocity, v, at it’s highest point is zero while it’s initial velocity u is given by;

Why is the direction of acceleration opposite to the velocity?

Acceleration is downward and velocity is upward for initial half of its areal time and after it reaches the highest point both the acc and velocity are in downward direction. When body goes upward→ The direction of acceleration is opposite to the velocity because of deacceleration.

Why velocity is zero at the highest point of a body?

When a body is thrown vertically upwards, at the highest point only velocity is zero because the acceleration due to gravitational force is acting downward continuously and that is the reason for velocity being zero at the highest point, hence velocity is zero because of the acceleration.
