Question

1/20
which activity would best demonstrate newtons law of inertia?
1
a plate sits on a table
top.
2
a lady pushes a
grocery cart.
3
a child jumps on a
trampoline.
4
a boy swings a baseball
bat.

Explanation:

Newton's law of inertia (1st law) states that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

• Option 1: A plate on a table is at rest. It remains at rest as no net external force (to move it) is acting, demonstrating inertia (object at rest stays at rest).
• Option 2: Pushing a cart involves applying a force to change its state (from rest to motion), which relates more to Newton’s 2nd law (force = mass×acceleration) or showing how force overcomes inertia, but not the best demonstration of inertia itself.
• Option 3: Jumping on a trampoline involves action - reaction (Newton’s 3rd law) and force to change motion, not inertia.
• Option 4: Swinging a bat involves applying force to change the bat’s motion, related to force and motion, not inertia.

So the activity that best demonstrates inertia is a plate sitting on a table (object at rest, no net force to change that state).

Answer:

1. A plate sits on a table top.
