It now lacks acceleration and is either maintaining constant speed or is decelerating.
It speeds up
When an object speeds up, it experiences positive acceleration.
In that case, the object speeds up.
The net force acting on the object determines how much it speeds up or slows down. If the force is in the same direction as the object's motion, it speeds up; if it's in the opposite direction, it slows down. The object's mass also plays a role, with more massive objects being harder to speed up or slow down.
it changes direction,it speeds up or slows down
True. When an object speeds up, its velocity increases, and therefore its momentum also increases. Momentum is the product of an object's mass and its velocity, so an increase in velocity results in an increase in momentum.
If a moving object is speeding up, the acceleration is in the same direction as the object's motion.
When an object speeds up, slows down, or changes direction, it is experiencing acceleration. Acceleration is the rate at which the velocity of an object changes over time. It can be caused by forces such as gravity, friction, or applied force.
Acceleration
Gravity speeds it up
Yes, changes in an object's speed, direction, or both involve acceleration. Acceleration is the rate of change of an object's velocity over time, where velocity includes both speed and direction. So, any time an object speeds up, slows down, or changes direction, it is experiencing acceleration.
The force that speeds up the movement of an object is typically the force of acceleration, which is generated by applying a driving force such as thrust, propulsion, or push. This force overcomes the resistance (friction, air resistance, etc.) to induce the object to move at a faster rate.
