what is mass times acceleration?
Answer:
Force
Explanation:
The mass of an object is the quantity of matter it contains. It is measured in kilograms.
Acceleration is the ratio of the change in the velocity of an object to the change in time. It is measured in m/[tex]s^{2}[/tex].
When the mass of an object is multiplied with its acceleration, this gives the average force applied on the object. As force is defined as agent that can change the state of an object.
i.e F = m × a
where F is the force, m is the mass of the object and a its acceleration.
The two major classes of force are; contact force and field force.

The diagram shows the field lines near the poles, X and Y, of two magnets.
At left a rectangular box with the long horizontal side labeled X. At right a rectangular box with the long horizontal side labeled Y. There is a gap between the boxes. Curved lines with arrowheads emerge from the right end of X and the left end of Y and point up and down.
Based on the field lines, what are the poles of the magnets?
X: north
Y: south
X: south
Y: north

What is the kinetic energy of a bicylcle with a mass of 15 kg traveling at a velocity of 3 m/s?
KE = 0.5 x mv^2
Kinetic energy equals 1/2 times mass times velocity squared.
Mass = 15kg
Velocity = 3m/s
Plug it into the formula.
KE = 0.5 x 15(3^2)
KE = 0.5 x 15(9)
Multiply the mass and velocity squared.
KE = 0.5 x 135
Then, multiply the result by 1/2 or 0.5
KE = 67.5
The kinetic energy of a bicycle that has a mass of 15kg and travels at 3m/s is 67.5J.
Answer:
67.5 J
Explanation:
Kinetic energy can be found using the following formula.
[tex]KE=\frac{1}{2}mv^2[/tex]
where m is the mass in kilograms and v is the velocity in m/s.
We know the bike has a mass of 15 kilograms. We also know the velocity is 3 m/s. Therefore, we can substitute 15 for m and 3 for v
[tex]KE=\frac{1}{2}*15*3^2[/tex]
Evaluate the exponent first. 3^2 is the same as 3*3, which is equal to 9.
[tex]KE=\frac{1}{2} *15*9[/tex]
Multiply 15 and 9.
[tex]KE=\frac{1}{2} *135[/tex]
Multiply 1/2 and 135
[tex]KE=67.5[/tex]
Add appropriate units. Kinetic energy uses Joules or J as the units.
[tex]KE= 67.5 Joules[/tex]
The kinetic energy of the bike is 67.5 Joules
