If it is sitting at the station, not moving, that would be a zero velocity AND zero acceleration. The instant it takes off from the station, it will have a zero-VELOCITY, but a non-zero Acceleration. As it continues to accelerate it will have a non-zero velocity AND a non-zero acceleration.

Constant Velocity

WebDoes a pendulum have constant velocity? As the pendulum bob does the back and forth, the velocity is continuously changing. There will be times at which the velocity is a negative value (for moving leftward) and other times at which it will be a positive value (for moving rightward). ... Does constant acceleration mean zero velocity? WebSep 20, 2024 · Does constant mean zero? More generally, any polynomial term or expression of degree zero (no variable) is a constant. ... That means if accelerations is zero, velocity must be constant. Now that constant could be anything like it could be 5 m/s . Also if the velocity is 0(which is itself a constant) also indicates that acceleration … WebModified 5 years, 11 months ago. Viewed 46k times. 2. According to Newton's second law, F = m a. If acceleration is zero then the force must be zero, but assuming you have an object moving with a constant velocity of say 2 m s − 1, and that object strikes you, then obviously some sort of 'force' would be felt by you, so my question is what do ... pictures of colonial beach virginia

WebJun 21, 2024 · With constant velocity, the force on the moving object is constant at the interval from the initial position to the final position, so the net change in force is zero. … WebNov 5, 2024 · An object with constant velocity has zero acceleration. A motionless object still has constant (zero) velocity, so motionless objects also have zero acceleration. Newton’s second law states that: \[\mathrm{∑F=ma}\] so objects with constant velocity also have zero net external force. This means that all the forces acting on the object are ...

WebSep 8, 2024 · The velocity of an object changes when the net force acting on it is not zero. When the net force is perpendicular to the velocity, it does no work and the kinetic energy of the object remains constant, so the force only changes the direction of velocity not the magnitude (speed). WebDec 18, 2015 · Constant velocity is a vector. A vector is a quantity that requires both a magnitude and direction to fully describe the quantity. For velocity, the magnitude refers to how fast the object is ...

Webacts on it. If the resultant force on an object is zero, this means: a stationary object stays stationary; a moving object continues to move at the same velocity.
