Kinematics
What is velocity?
This quantity measures how fast an object is moving and in what direction.
What is natural selection?
This term describes the survival and reproduction of individuals best adapted to their environment.
What is a chemical reaction?
This type of reaction involves the formation of new chemical bonds and the rearrangement of atoms.
What is DNA?
This molecule carries genetic information and is known as the blueprint of life.
What is Newton's First Law of Motion?
This law states that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.
What is acceleration?
The rate of change of velocity is referred to as this.
Who is Charles Darwin?
This scientist is known for formulating the theory of natural selection alongside his work on the origin of species.
What is the law of conservation of mass?
This law states that matter cannot be created or destroyed in a chemical reaction.
What is a phenotype?
The physical expression of a gene, such as eye colour, is referred to as this.
What is Newton's Second Law of Motion?
This law describes the relationship between an object's mass, its acceleration, and the net force acting on it.
What is displacement?
This is the term for the change in position of an object over time.
What is variation?
This concept refers to the range of traits in a population that can change based on environmental pressures, leading to adaptation.
What is a synthesis reaction?
This type of reaction occurs when two or more substances combine to form a single product.
What are alleles?
This term describes alternative forms of a gene that can produce variations in a trait.
What is Newton's Third Law of Motion?
According to this law, for every action, there is an equal and opposite reaction.
What is speed?
This quantity measures how fast an object is moving, regardless of direction.
What is adaptation?
This concept describes how a population can become better suited to its environment through the accumulation of advantageous traits over time.
What is a decomposition reaction?
In this type of reaction, a single compound breaks down into two or more products.
What is meiosis?
This type of cell division results in gametes with half the number of chromosomes.
What is mass?
his concept explains why a heavier object requires more force to accelerate than a lighter one, assuming the same acceleration.
What is constant speed?
A straight line on a position-time graph indicates that an object is moving at this speed.
What is selective pressure?
This occurs when individuals with certain traits are more likely to reproduce than others in the same population.
What is activation energy?
This term describes the energy required to start a chemical reaction.
What is a genotype?
The genetic makeup of an individual, including both dominant and recessive alleles, is called this.
What is static friction?
This type of friction acts on objects that are not moving.
