What does "balance" mean in the context of a seesaw?

• Balance means both sides of the seesaw are at the same height

• Balance is achieved when the weights on both sides are equal

• The seesaw is balanced when one side is heavier than the other

• Balance is when the seesaw is not moving

What does "Equal forces" mean in the context of a tug-of-war game?

What is gravity and how does it affect our lives?

• Gravity is caused by the rotation of the Earth
• Gravity is a fictional concept created by scientists
• Gravity only affects objects in space, not on Earth
• Gravity is the force that attracts objects with mass towards each other. It affects our lives by keeping us grounded on Earth, allowing objects to fall, and influencing the motion of celestial bodies.

What are the important differences between the Scientific and Non-scientific meanings of

‘inertia’?

• Inertia is only relevant in scientific contexts
• Inertia has the same meaning in both scientific and non-scientific contexts
• Inertia is a term used exclusively in non-scientific discussions
• The important differences between the Scientific and Non-scientific meanings of 'inertia' are related to motion and resistance to change in the scientific context, while in the non-scientific context, it refers to a lack of activity or willingness to change.

What is the relationship of force, mass, and acceleration?

• Force is directly proportional to both mass and acceleration.
• Acceleration is directly proportional to mass but inversely proportional to force.
• Mass is directly proportional to force but inversely proportional to acceleration.
• Force is inversely proportional to mass and acceleration.

What is the relationship between force and acceleration?

• Force has no effect on acceleration

• Force increases acceleration linearly

• Force decreases acceleration exponentially

• Force affects acceleration by making it larger for a given mass.
