Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a compressed spring has potential energy because it can do work when released.

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.

Front

How does mass affect motion?

Back

The greater the mass of an object, the more force is needed to change its motion. Heavier objects are harder to move and require more force.

Front

What is the relationship between force and motion?

Back

Force is a push or pull that can cause an object to move or change its motion. More force results in greater acceleration.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other. On Earth, it pulls objects toward the center of the planet.

Front

What happens to an object's speed when it goes downhill?

Back

An object's speed increases when it goes downhill due to the force of gravity acting on it.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact. It can slow down or stop moving objects.

Front

What is the effect of adding mass to a shopping cart?

Back

Adding mass to a shopping cart makes it more difficult to move because it requires more force to push.

Front

What is the best way to lift a heavy object with a shovel?

Back

The best way to lift a heavy object with a shovel is to use proper technique, such as bending your knees and keeping your back straight.

Front

What is the path of a marble launched by a spring?

Back

The marble will follow a curved path as it is propelled forward by the spring's force.
