What else can I help you with?
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.
Do forces result motion?
YES
Why do some objects move continuously while some moving objects stop suddenly?
Because of friction, Friction is what causes moving objects to slow down and eventually stop. This is an important science idea we can use to describe the force that pushes back on a moving object and makes it slow down and stop.
What objects have no kinetic energy?
Objects that are at rest have no kinetic energy. Additionally, objects that have come to a complete stop after moving previously also have no kinetic energy.
What will happen to moving objects if there is no friction?
Without friction, moving objects will continue to move at a constant velocity in a straight line, as there would be no force to decelerate or stop them. These objects would essentially keep moving indefinitely unless acted upon by an external force.
How do objects start moving?
Objects start out as either a rest or moving. If they are at rest, they require a force to be applied for them to start moving. If they are moving, they require a force to either slow them down or to make them stop. That means that once something starts moving, it will move forever, unless a force slows it down. The catch is that the force can be friction.

Do forces result motion?
YES
Does Friction bring many moving objects to a stop?
yes

Does friction partially stop or completely stop two objects moving at the same speed towards each other?
friction slows objects down but because of that it eventually brings them to a stop
What force can cause an object to start moving also stop moving?
Gravity
What objects have no kinetic energy?
Objects that are at rest have no kinetic energy. Additionally, objects that have come to a complete stop after moving previously also have no kinetic energy.
What are the forces around you?
Forces are pushes or pulls. They can start objects moving, they can stop,speed up, slow down, or change the direction of moving objects. They can lift things, or cause them to turn, bend or twist. They can also prevent motion; eg. a handbrake on a car stops it from rolling down the hill.
Can cause an object to start moving stop moving or change directions?
A force or acceleration
