Why is more force needed to change the motion of a heavy and fast moving object compared to a light weight and slow moving obect?
More force is needed to change the motion of a heavy and fast-moving object because of its momentum, which is the product of its mass and velocity. The momentum of an object indicates the amount of force required to change its motion, so heavier objects with higher velocities require more force to change their direction or speed compared to lighter objects moving at slower speeds.

Why are heavier objects harder to start or stop moving?
Heavier objects have more inertia, which means they resist changes in their motion. More force is needed to start or stop the motion of a heavier object compared to a lighter one.
Why do you need a reference to know that an object is in motion?
A reference frame is needed to determine an object's motion because motion is relative. An object is in motion only when compared to another object or a specific frame of reference. Without a reference point, it's impossible to determine if an object is moving or stationary.
Why is less force needed to keep an object moving than to start the object in motion?
1). Because maintaining an object in motion requires no force, but causing a non-moving object to move involves acceleration which does require force. 2). Because kinetic friction is generally less than static friction.
What law of motion does this describe A small car is easier to start moving than a large car?
This observation can be explained by Newton's second law of motion, which states that the force required to accelerate an object is directly proportional to its mass. A smaller car has less mass, so less force is needed to get it moving compared to a larger car.
Why no force is needed to maintain motion?
According to Newton's first law of motion, an object in motion will remain in motion unless acted upon by an external force. This means that if no external force is applied to an object, its motion will not change. So, if an object is already moving, it will continue to move at a constant velocity without the need for a force to maintain that motion.
Is net force needed to change the speed or direction of moving matter?
Yes, a net force is needed to change the speed or direction of moving matter. Newton's first law of motion states that an object will remain in its state of motion unless acted upon by an external force. When a net force is applied, it can accelerate the object, decelerate it, or change its direction.

What is the amount of force needed to keep a ball moving that has been launched into frictionless space?
In the vacuum of frictionless space, no force is needed to keep the ball moving. According to Newton's First Law of Motion, an object in motion will stay in motion unless acted upon by an external force. Therefore, once the ball is launched into frictionless space, it will continue moving indefinitely.
A force is needed to change the motion of an object?
Yes, an unbalanced force is needed to change the motion of an object.If an unbalanced force does not act on an object it will continue to maintain its state of motion (either in motion or at rest), not considering the effect of frictional force. This is basically Newtons first law of motion.
Is the frictional force needed to slow and object in motion?
Yes, frictional force is needed to slow down an object in motion. When an object is moving, friction acts in the opposite direction of its motion, leading to a decrease in its speed until it comes to a stop.
What type of force is needed to cause a change in an object's motion?
A net force from something outside of the system.
Why is less force neede needed to keep an object moving than to start the object in motion.?
The best, purest answer is: Because no force at all is required to keep a moving object moving.
