Yes, because gravity always exerts a force whether an object is at rest or in motion. Gravity is the reason we aren’t all floating as cool as that would be we would probably be hit by a plane

What can you find using newton's three laws of motion
topjm [15]

Answer:

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Explanation:

hope this helps! :)

A child does a 12 j of work pushing his 3kg toy truck with what velocity does the toy move after the child done pushing
densk [106]
We have to assume that the truck was not moving
before he started pushing it.

After he did 12 J of work pushing it, the truck had
12 J of kinetic energy.

                                         Kinetic energy = (1/2) (mass) (speed²)

                                                12 J              =  (1/2) (3 kg) (speed²)

Divide each side by 1.5 kg :  12J / 1.5 kg = speed²

1 J = 1 newton-meter           (12 kg-m²/sec²) / (1.5 kg) = speed² 
      =  1 kg-m² / sec²                                     
                                               (12 / 1.5) ( m²/sec²)  =  speed²                                             

                                               Speed = √(8 m²/s²)

                                               Speed  =   2.83 m/s .

We can't say anything about velocity, because we don't know
anything about the direction in which the truck is moving.
