## When an object is released from a certain height?

When an object is released from a cetain height, then it experiences a resistive force (Fv) which is called viscous force or air drag, and the force is directly proportional to the velocity of the object at any time.

## How far has an object fallen after one second of freefall?

4.9 m

The first equation shows that, after one second, an object will have fallen a distance of 1/2 × 9.8 × 12 = 4.9 m.

**When an object comes to rest at the end of its motion what is its final velocity?**

Answer: The final velocity (v) of the object will be zero when it will come to rest.

**When and in object is released from a height it possesses energy?**

Detailed Solution. An object is released from a certain height above the ground. Just at the time it touches the ground, it will possess kinetic energy. When the body falls from height potential energy decreases but kinetic energy increases but overall energy remains constant.

### When an object is released from a height its initial velocity is?

zero

Initial velocity of a body when dropped from a height is zero, i.e., u=0.

### How far does an object in free fall move in the first 1.00 seconds after release?

The magnitude of the acceleration due to gravity, denoted with a lower case g, is 9.8 m/s2. g = 9.8 m/s2. This means that every second an object is in free fall, gravity will cause the velocity of the object to increase 9.8 m/s. So, after one second, the object is traveling at 9.8 m/s.

**When an object comes to rest at the end of its motion its initial velocity is zero True or false?**

The final velocity will be 0 m/ s as the object is at rest and is not moving with respect to time.

**What happens when two bodies are released from the same height?**

A body is released from a great height and falls freely towards the earth. Another body is released from the same height exactly one second later. The separation between the two bodies, two seconds after the release of the second body is [CPMT 1983; Kerala PMT 2002] An object is projected upwards with a velocity of 100 \\ [m/s\\].

#### What happens when two objects are dropped at the same time?

If two objects are held, one under the other, and dropped at the same time, they will keep the same distance between them. (OK, almost or good enough — ignoring the gravity between the two objects). If two objects are dropped in tandem one second apart … This strongly suggests that the distance increases over time (until the hit).

#### What is the displacement of the stone from the point of release?

The displacement of the stone from the point of release after 10 sec is A ball is dropped on the floor from a height of 10 m. It rebounds to a height of 2.5 m. If the ball is in contact with the floor for 0.01 sec, the average acceleration during contact is [BHU 1997; CPMT 1997] A body A is projected upwards with a velocity of \\ [98\\,m/s\\].

**What happens when a ball is released from the same height?**

An iron ball and a wooden ball of the same radius are released from the same height in vacuum. They take the same time to reach the ground. The reason for this is A body is thrown vertically upwards. If air resistance is to be taken into account, then the time during which the body rises is [RPET 2000; KCET 2001; DPMT 2001]
