18 Weeks 6th Grade Science Misconceptions

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal in size and direction, resulting in a net force that causes the object to accelerate.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

How does energy transform in a hydroelectric power plant?

Back

In a hydroelectric power plant, gravitational potential energy of water is converted to kinetic energy as it flows down, which then spins turbines to generate electrical energy.

Front

What does Newton's first law of motion state?

Back

Newton's first law states that an object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by an external force.

Front

What is friction?

Back

Friction is a force that resists the motion of two surfaces that are in contact with each other.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion, which depends on its mass and velocity.

Front

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

Back

According to Newton's second law, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, which can be released during a chemical reaction.

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined, determining the object's acceleration.

Front

What is an example of an action-reaction pair according to Newton's third law?

Back

When a person jumps off a small boat, the action is the person pushing down on the boat, and the reaction is the boat pushing the person upward.
