Exploring the Centre of Gravity through Experiments

What is the scientific term for balance?

• Stability

• Center of Gravity

• Symmetry

• Equilibrium

What happens to the center of gravity when a dime is added to the spoon?

• It becomes unstable

• It disappears

• It shifts to a new position

• It remains the same

How can you find the center of gravity of an object?

• By weighing it

• By hanging it and drawing lines

• By measuring its dimensions

• By spinning it

Why is it easier to balance a potato with forks inserted into it?

• The forks add weight

• The forks alter the center of gravity

• The forks make it lighter

• The forks change the shape

What principle allows checkers to be knocked out of a stack without the stack falling?

• Momentum

• Friction

• Inertia

• Gravity

What does Newton's first law of motion state?

• Force equals mass times acceleration

• Energy cannot be created or destroyed

• An object at rest stays at rest, and an object in motion stays in motion

• For every action, there is an equal and opposite reaction
