The forces acting on a falling leaf are

Answers

Answer:

Gravitational and resistance force.

Explanation:

The push or pull on any object which causes an object to move is called force. The forces can be of many types. The forces acting on the falling leaf are :

  • Gravitational force : The force that acts in downward direction is called the force of gravity. This force pulls every object towards it.
  • Resistance force/ normal : The force that act opposite to gravitational force is called the resistance force. It opposes the direction of motion of the leaf.
the forces acting on a leaf are gravity and air resistance.In some cases the only force acting on an object is gravity, if that occurs then its called freefall. 

In the steps of the scientific method, what is the next step after formulating and objectively testing hypotheses?A. interpreting resultsB. stating conclusionsC. conducting experimentsD. making observations and collecting data

Answers

Answer:

Option A

interpreting results

Explanation:

In a Scientific research, we first formulate and test hypothesis of the study. A hypothesis is a tentative guess in the study which should be validated in the process of the study. We may have a null and alternative hypothesis. After formulating the study, we conduct the actual study where we get raw data. The raw data is then analyzed, in many cases using statistical analysis tools such as R, python, excel spreadsheet etc. Therefore, the next step after formulating and objectively testing hypotheses is to interpret the results.

In the steps of the scientific method, the next step after formulating and objectively testing hypotheses is interpreting results.

Scientific method is an experimental method used in scientific research for evaluating a scientific hypothesis. The process of carrying out scientific method involves observation, then asking questions, followed by finding answers via carrying out experiments.  

The steps involved in the carrying out scientific methods includes the following processes:

  • observation or asking question
  • research topic formulation
  • formulating hypothesis
  • testing hypothesis or experimentation
  • interpreting or analyzing  result
  • report and conclusion

Therefore, we can conclude that in the steps of scientific methods, the next step after formulating hypotheses is interpreting results.

Using information about natural laws, explain why some car crashes produce minor injuries and others produce catastrophic injuries.

Answers

The larger the mass and the speed, the larger the force it would produce if it crashes something. Some car crashes produce minor injuries because maybe this car is small and runs at very slow speed which would mean less force when in impact with another. However, if a big truck crashes, it is expected to produce a larger force causing catastrophic injuries.

The car crash in which the car is moving at higher speed will cause catastrophic injuries whereas the car moving at smaller speed will cause minor injuries. This is due to the law of inertia of the bodies.

Explanation:

The inertia of a body is defined as the resistance of the body towards any change in its current state of rest or motion. The body does not want to change its state and this resistance of the body is directly proportional to the mass of the body.

According to the law of inertia, a body continues to be in its state of rest or motion until and unless an external force acts on the body.

A car moving at a higher speed and having a higher mass is considered to have higher inertia of motion and therefore when it crashes, it experiences a very high stopping force and due to this, the injuries caused in the car crash will be very catastrophic.

Whereas, if the same car is moving at a lower speed, the inertia of motion of the car will be less and when this car crashes, it will experience a smaller force and comes to rest. Due to this, the injuries caused in the crash will be minor.

Thus, The car crash in which the car is moving at higher speed will cause catastrophic injuries whereas the car moving at smaller speed will cause minor injuries. This is due to the law of inertia of the bodies.
