    Explanation:

    Newton’s Second Law of Motion

    Newton’s Second Law of Motion states that ‘when an object is acted on by an outside force, the mass of the object equals the strength of the force times the resulting acceleration’.

    This can be demonstrated dropping a rock or and tissue at the same time from a ladder. They fall at an equal rate—their acceleration is constant due to the force of gravity acting on them.

    The rock's impact will be a much greater force when it hits the ground, because of its greater mass. If you drop the two objects into a dish of water, you can see how different the force of impact for each object was, based on the splash made in the water by each one.

  2. Sam's bike hits a curb and he flies over the handlebars, onto the grass.

    Explanation:

    As we know that: Newtons first law of motion states that a body continues to remain in the inertia of rest or motion, unless it is forced to change by applying an unbalanced force. Sam's bike is in uniform motion when suddenly the curb(external force) hits it and makes Sam to fall.

  3. Many people express themselves through their hair. They can braid it, cut it, leave it down or color it based on their style and the type of person they are. Some choose to dye it bright colors or shave their hair completely. No one can tell them what to do with their hair.

  4. I think it's A person sits on a chair and pushes down, and the chair pushes upwards on the person. It makes the most sense when applied

  5. I think first one

    Explanation:

    Because his first law of motion was every object will remain at rest or uniform motion in a straight line
