The energy expended depends on various factors like the mass of the Baseball, its velocity, air resistance, and other forces acting on it. However, if we assume ideal conditions, you can calculate the energy using the formula for kinetic energy: KE = 0.5 * mass * velocity^2. Once you have the kinetic energy value in joules, you can compare it to the energy expended by the baseball as it travels 30 meters.

How many watts in 7000 joules?
To convert joules to watts, you need to know the time over which the energy is expended. Since power in watts is defined as energy in joules divided by time in seconds, you cannot directly convert 7000 joules to watts without knowing the time duration.
What does the term energy expended over time mean in physics?
In physics, energy expended over time refers to the rate at which energy is used or transferred. This is typically measured in units like watts (Joules per second) to quantify how quickly energy is being consumed, produced, or transformed in a system.
What is 6 million joules in watts?
To convert joules to watts, you need to know the time period over which the energy is expended. Watts = Joules / seconds. Without this information, it is not possible to directly convert 6 million joules to watts.
What is the difference between joules and watts?
Joules (J) measure energy, while watts (W) measure power. Power is the rate at which energy is expended or transferred, so 1 watt is equal to 1 joule per second. In other words, watts represent the amount of energy consumed or produced per unit of time.
What is the conversion from joules of energy to watts of energy?
Power (watts) is a measure of energy transfer over time, while energy (joules) is a measure of total work done. The formula to convert energy in joules to power in watts is: Power (watts) = Energy (joules) / time (seconds).
How many watts in 7000 joules?
To convert joules to watts, you need to know the time over which the energy is expended. Since power in watts is defined as energy in joules divided by time in seconds, you cannot directly convert 7000 joules to watts without knowing the time duration.
How much energy in joules is expended how much work is done if a baseball travels a distance of 30 meters?
Not enough information given to nail down an answer. 'Work' in physics is defined as force acting through a distance. The question says nothing about the forces on the baseball, and doesn't tell us anything about the direction of the 30-meters' travel, which we could use to calculate the work done on it by gravity.
What does the term energy expended over time mean in physics?
In physics, energy expended over time refers to the rate at which energy is used or transferred. This is typically measured in units like watts (Joules per second) to quantify how quickly energy is being consumed, produced, or transformed in a system.
How much energy is expended in moving a 20 coulomb charge through a potential difference of 0.5 volts?
To calculate the energy expended in moving a charge through a potential difference, you can use the formula: Energy (E) = Charge (Q) × Potential Difference (V) Given: Charge (Q) = 20 Coulombs Potential Difference (V) = 0.5 Volts Plugging in the values: E = 20 C × 0.5 V E = 10 Joules Therefore, the energy expended in moving a 20 Coulomb charge through a potential difference of 0.5 Volts is 10 Joules.
Is energy a performance of work?
Yes, simply. Work done (mechanically, electrically) is numerically equal in joules to the energy expended as the work is being done. Think of it as two halves of the same coin.
What is 6 million joules in watts?
To convert joules to watts, you need to know the time period over which the energy is expended. Watts = Joules / seconds. Without this information, it is not possible to directly convert 6 million joules to watts.
What is the unite of energy?
the energy unit is called joules
How much electricity does 10kw have?
A power of 10 kW or 10,000 watts means that 10,000 Joules of energy is converted every second. In 1 hour the energy expended is 10 kilowatt-hours which would appear as 10 units on the electricity bill.
What is the difference between joules and watts?
Joules (J) measure energy, while watts (W) measure power. Power is the rate at which energy is expended or transferred, so 1 watt is equal to 1 joule per second. In other words, watts represent the amount of energy consumed or produced per unit of time.
A pitcher throws a 250g baseball to make it accelerate to 50 ms the instant it leaves his hand How much energy in Joules is expended how much work is done if that baseball travels 60 feet?
?
What is the metric unit for measuring energy?
Joules are the metric units used to measure energy. When you are working with any form of energy you state them in joules.
How many watts does 2400 joules equal?
To convert joules to watts, you need to know the time over which the energy is expended. Watts are a unit of power, which is energy per unit time. If the time is known, you can use the formula: Watts = Joules / seconds.
