Yes, but it will have a non-zero velocity afterwards.
Velocity sufficient for a body to escape from a gravitational attraction without acceleration. Earth has an escape velocity of 11.19 kmsec-1 .
The speed is the MAGNITUDE of the velocity, i.e., without regard to the direction.
Yes. Velocity is rate (or speed) in a given direction. If you change your direction but not your rate (or speed) then you have changed your velocity without changing speed.
A force changes a body's velocity.
False. A body traveling at constant speed does not change its velocity, which includes both speed and direction. Therefore, in order to change direction, the body would need to change its velocity, which also involves changing its speed.
Yes, a body can have aceleration without velocity. Consider sin x the position; cos x is the velocity and -sin x is the acceleration. Here the acceleration negative when x=90 degrees and the velocity is zero at 90 degrees.
Yes. If a body has a constant velocity there is no acceleration, but if the velocity is changing there is acceleration present.
Gravity affects velocity by changing the acceleration of an object. As an object falls, gravity accelerates it, increasing its velocity. Without gravity, an object would move at a constant velocity.
Escape velocity is the minimum speed an object must achieve to break free from the gravitational pull of a celestial body, such as a planet or moon, without further propulsion. It allows the object to escape the body's gravitational field and travel into space. The escape velocity varies depending on the mass and size of the celestial body.
Speed and velocity become equal when an object is moving in a straight line without changing direction or when it is moving at a constant speed. Velocity is a vector quantity that includes both speed and direction, so if the direction of motion is constant, speed and velocity will be the same.
When a body has constant velocity, the acceleration is zero. This is because acceleration is the rate at which velocity changes, so if velocity is constant, there is no change and hence no acceleration.
The 'speed' of a body cannot be negative. But if you are stating the 'velocity' then it can be negative. Negative velocity means it is going opposite to the direction that you decided to call the positive direction.
