∙ 14y agoNewton's Second Law of Motion states that Force equals the product of mass and acceleration. Thus, the force required to accelerate a 200 kg object 15 meters per second squared equals 200*15. This is equivalent to 300 Newtons.

∙ 14y agoSurface area is the sum of the areas of all the surfaces of an object. When you add units, they stay the same. Since you are adding, let's say, meters squared and meters squared and meters squared, your unit is still meters squared. Volume is a measure of how much space is inside an object. To find volume, you must multiply length, width, and height. In our example, that would be meters x meters x meters. When you multiply units, they multiply to each other. So, we get meters cubed, or meters^3.
There is some confusion here. 500 newtons IS a force. You don't "give a force an acceleration". You can accelerate an object (which has a mass), but not a force.
It means that the object's speed is always 5 meters per second faster than it was one second earlier.
-2.33 metres per second squared
Convert 78 mph to meters per second: 78 mph=35 meters/second The acceleration of earths gravity is 9.8 meters per second squared. This is constant. Therefore, using basic calculus, the velocity of a falling object is equal to 9.8 meters per second times the time it has fallen. 9.8*T=35 T=3.6 Thus, it takes roughly three and a half seconds for the average human body to accelerate to 78 miles per hour (assuming wind drag is inconsequential).
One newton.
No, it is not harder to accelerate a moving object. The initial motion of the object does not affect the force required to accelerate it further. The force required to accelerate an object depends on its mass and the desired acceleration.
F = ma so F = 10kg x 6m/s^2 = 60 kgm/s^2 or 60 Newtons
F = ma, so if mass is constant, you need to double the force to double the acceleration. The answer is 20 N.
It doesn't. Close to Earth's surface, any object will accelerate towards the center of the Earth at a rate of about 9.8 meters/second squared, regardless of the object's mass.
False. A balanced force does not accelerate an object, but an unbalanced force is required to change the motion of an object.
The acceleration of the object can be calculated using Newton's second law: acceleration = Force / Mass. Plugging in the values, we get acceleration = 1272 N / 212 kg = 6 m/s^2. So, the object will accelerate at 6 meters per second squared.
No, it takes the same force to accelerate a moving object as it does to accelerate a stationary object, according to Newton's first law of motion. The force required depends on the mass of the object and the desired acceleration.
No. To have an acceleration, an UNBALANCED force is required.

Objects in free fall accelerate at a rate of 9.8 m/s^2 (meters per second squared) due to gravity near the surface of the Earth. This acceleration is constant regardless of the object's mass.
If you throw an object downward, its acceleration will be greater than 9.8 meters per second squared because you are adding to the acceleration due to gravity. The initial velocity from the throw adds to the gravitational acceleration, resulting in a faster overall acceleration downward.
