A projectile is launched from the ground. Assuming that air resistance is negligible, which of the following statements is FALSE?

The motion involves constant velocity along the horizontal and constant acceleration along the vertical.

The vertical component of the velocity along the motion is constant.

The horizontal component of the velocity along the motion is constant.

The path made by the projectile is a parabolic.

Linear momentum is a

scalar quantity

force

product of velocity and mass

product of mass and acceleration

The principle of conservation of linear momentum states that

the total initial momentum of all objects interacting with one another is not equal the total final momentum

the total initial momentum of all objects interacting with one another is equal to the total final momentum.

the total initial momentum of all objects interacting with one another is more than the total final momentum

the total momentum of all objects interacting with one another is always remains not conserved

Elastic collision and inelastic collision can be differentiated by

kinetic energy

momentum

force

impulse
