What do we call the force that pulls objects towards the Earth?

• Friction

• Gravity

Answer explanation

The force that pulls objects towards the Earth is called gravity. It is a fundamental force that attracts two bodies towards each other, with Earth exerting a strong gravitational pull on objects near its surface.

What is the term for the speed of an object in a specific direction?

• Motion

• Reaction

Answer explanation

The term for the speed of an object in a specific direction is 'motion'. It describes not just how fast an object is moving, but also the direction in which it is moving, making it distinct from other concepts like reaction.

What do we call energy that is stored?

• Potential

• Electrical

Answer explanation

Energy that is stored is called potential energy. It represents the energy held by an object due to its position or state, distinguishing it from energy in motion, such as kinetic energy.

What is it called when something moves up?

• Create

• Ascend

Answer explanation

The term 'ascend' specifically refers to the action of moving up, making it the correct choice. 'Create' does not convey upward movement, thus 'ascend' is the appropriate answer.

What is the opposite of accelerate?

• Decelerate

• Destroy

Answer explanation

What do we call the energy that comes from the sun?

• Mass

• Solar

Answer explanation

What is a vehicle that travels under water?

• Submarine

• Rocket

Answer explanation

What do we call the change of one form of energy to another?

• Mass

• Conversion

Answer explanation

The change of one form of energy to another is called 'Conversion'. This term describes the process of transforming energy from one type to another, such as from kinetic to potential energy.

What is the term for the force that slows down moving objects?

• Brake

• Turn off

Answer explanation

The term 'brake' refers to the mechanism or force that slows down or stops moving objects, making it the correct choice. 'Turn off' does not specifically relate to slowing down motion.
