Question

what are 1. free fall 2. acceleration due to gravity 3. escape velocity 4. centripetal force........ plzzz answer fast friends ... urgent

Answer 1

1 down word momentum under the force of gravity only.

3 the lowest velocity which a body must have in order to escape the gravitational attraction of an object.

4 centripetal force is a net force that acts on an object to remain in circular path.

Answer 2

Hello here is your answer...

Free Fall

According to physics when only force of gravity acts on you then it is called as a free fall. The speed of the free fall can be 200km/h (120mps) .
Eg. Skydiving

Acceleration due to gravity

The acceleration which is gained by an object because of the gravitational force is called its acceleration due to gravity. Its SI unit is m/s2

The value taken is 9.8m/s2.

Escape Velocity

The maximum velocity required to escape from the gravitational force of the earth is called escape velocity.

The escape velocity from Earth is about 11.186 km/s (6.951 mi/s; 40,270 km/h; 25,020 mph) at the surface.

Eg Rockets at take off

Centripetal Force

Centripetal force is defined as the force required to make an object move on a curved path without changing its speed .

Eg Rotating circular swings.

Hope this helps ✌✌
