Question

an object moving with constant speed on a horizontal surface will not have?
A) Velocity
B) momentum
C) KE
D) acceleration

Answer 1

Hello mate!!
The answer is option D) acceleration
because the speed is constant.
I hope it helps you....

Answer 2

An object moving with constant speed on a horizontal surface will not have acceleration.

• Velocity is the rate of change of position of the object. And since here the object is moving on a horizontal surface it can have a constant velocity.
• Momentum is measured as the product of mass and velocity. Here the object will have a certain mass and is having some velocity so it will have some momentum.
• KInetic energy is the energy possessed by the object in motion and since the object here is moving so it will have kinetic energy.
• Acceleration is the rate of change of velocity and here since the velocity is constant so it will not have any accerelation.
• So the object here will not have any acceleration.
