Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another, allowing for motion or change in the state of the objects.

Front

What happens when gear 1 is turned in a machine?

Back

When gear 1 is turned, it transfers energy to gears 2 and 3, causing them to move in the directions indicated.

Front

What is the effect of mass on motion?

Back

The greater the mass of an object, the more force is required to move it. This means that as mass increases, it becomes more difficult to move the object.

Front

What is the role of gravity in a seesaw?

Back

Gravity pulls down on the objects on the seesaw, creating a balance of forces. When one side is pushed down, the force on that side increases, causing it to move.

Front

What is a spring's potential energy?

Back

A spring stores potential energy when it is compressed or stretched. This energy is released when the spring returns to its original shape, launching an object.

Front

What is the relationship between force and motion?

Back

Force is what causes an object to move or change its motion. The greater the force applied, the greater the change in motion.

Front

What is friction?

Back

Friction is the resistance that one surface or object encounters when moving over another. It can slow down or stop motion.

Front

How does mass affect the distance an object rolls?

Back

When rolling objects of the same size but different masses, the lighter object will generally roll farther when the same force is applied.

Front

What is the principle of balance in a seesaw?

Back

A seesaw balances when the weight on both sides is equal, allowing it to remain level without moving.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.
