Objects in rest/motion remain in that state unless acted upon by an outside force.
An object at rest or in motion stays in that state unless acted on by an outside force. If you rolled a bowling ball, it would roll forever if friction, gravity, and air resistance were not pushing back on it. The same is true for an object at rest. An object at rest will not move unless a force acts upon it like a push or a pull. Let´s say you push a tire down a gravel road. This tire will not go very far because gravel has much more friction acting on it, making it stop. If you rolled the same tire down pavement, it would go father because there is less friction.
If you ride a bike down a street and stop pedalling, the bike will eventually stop because of friction from the tires.
The object will move in the direction that has more force.
There is only motion if there is unbalanced force. This means that the forces acting on an object are not equal.If on object is being pushed on from the east with 250 Newtons and from the west 300 Newtons, the total Newtons would be -50. Only when the forces are uneven will there be motion.
If I arm wrestle someone stronger than me, they will put more force on my arm and my arm will go down.
One of the objects could have more speed.
A smaller object is more likely to exert less force than and object with greater mass. However, if the smaller object has more speed it can exert the same amount of force as the larger one. More speed means more force.
If you kick a tennis ball really hard and it hits a soccer ball, the tennis ball can exert more force.
