1. during a collision, the person not wearing a seatbelt is already in motion. there is no outside force (the seatbelt) to stop this motion.
2. Kinetic Energy = 0.5 * m * v^2 because velocity is a squared term, doubling the velocity actually quadruples the kinetic energy, making the stopping distance much much greater
3. by the same logic as above, mass is not a squared term, therefore doubling the mass will double the kinetic energy, increasing the stopping distance -- but by not as much as increasing the velocity.
4. because a driver cannot alter the mass of his vehicle, the best way to enter sharp curves would be decreasing velocity (speed)
5. there are many factors that determine the degree of damage (to humans and property in a crash), most notably the size of the vehicle(s) and velocity.
Whenever creating a professional action plan, it might be easier to do an "if...then..." plan, or just a daily plan, like this:
Monday:
Kitchen:
Do dishes
Sweep floor
Wipe counters
Bedroom:
do laundry etc,
Expressions provide an easy way to perform operations on data values to produce other data values, True.
<h3>
What is an Expression? </h3>
An expression is a combination of one or more operands (Constant, Variable, Array element, Function), operators(Multiplication,Division, Subtraction etc) to be interpreted by a programming language following rules of precedence or association to produce other data values.
Three kinds of expressions includes:
- A logical or relational expression
Therefore, it is true that Expressions provide an easy way to perform operations on data values to produce other data values.
