As you increase the force applied to a rolling ball the acceleration of the ball increases this is an example of what law?
if you increase the force , the mass remaining constant, a new rate of acceleration applies in the order a = f/m from that point (second law)
What happens to acceleration if both mass and force remian constant?
Since acceleration = force / mass, it will fall as mass increases.Progressive loss of mass is much more likely to occur in real life - for instance with a rocket, which burns fuel as it goes. In this case, acceleration will increase.
What 2 things increase as kinetic energy increases?
Generally speed. But also, if the obect is for example travellin up, the potential energy also increases.
What is the definition for direct proportional?
Direct proportional means as one value increases the other value increases as well. For example, if add mass into a plastic bag the bag will expand/stretch therefore if mass increase the streching will increase as well. Hope you find it helpful!
When will you say a body is in uniform acceleration and non-acceleration?
"Uniform acceleration" means that acceleration doesn't change over time - usually for a fairly short time that you are considering. This is the case, for example, when an object drops under Earth's gravity - and air resistance is insignificant. "Non-uniform acceleration", of course, means that acceleration does change over time.

Why does speed increase?
Speed increases when a body accelerates under the influence of a force. Newton's second law: acceleration= force/mass. Acceleration is the rate of change of speed over a period of time. For example if you drop an object, it's speed increases by 9.8 meters per second every second.
What is one example of negative acceleration?
A car slowing down when the brakes are applied.
What is an example of average acceleration?
All acceleration in real life is an average figure = velocity increase / time
How does aircraft drag increase with speed?
Drag increases by the square of velocity increase, for example, tripling speed increases drag by a factor of nine!
Give you an example in which acceleration is against the direction of motion?
Brakes are applied while the car is travelling north. Acceleration is toward the south, car slows down.
Can a moving body have velocity and acceleration in opposite directions explain with in example?
Of course. A car with brakes applied and slowing down has forward velocity and rearward acceleration.
''How do calculate velocity?
To calculate velocity using acceleration, start by multiplying the acceleration by the change in time. For example, if the acceleration is 10 m/s2 and the change in time is 5 seconds, then there is a 50 m/s increase in velocity. Then, add the initial velocity to the increase in velocity.
How can acceleration be constant if it is an increase in speed?
Exactly the same way that the speed can be constant but the distance keeps increasing.If the acceleration happens to be an increase in speed, then "constant" accelerationmeans that the speed will increase just as much in the 7th minute, for example,as it increased in the 4th minute, for example, etc.Acceleration can be the rate at which speed changes. So if the acceleration is constant,then the speed is changing at a constant rate.(Note: Acceleration doesn't have to be a change of speed. It can also be a changeof direction, at constant speed.)
How many times centripetal force will increase if the angular speed of a body moving with uniform speed moving in a circle is increases?
Centripetal acceleration, and therefore centripetal force, is proportional to the square of the angular velocity. For example, if you increase the angular velocity by a factor of 10, the centripetal force will be increased by a factor of 100.
What is steric acceleration?
For Sn1 reaction the rate usually increases due to steric acceleration. For example the more methyl groups a compound has i.e the more tertiary it is the faster the rate of reaction will be for an Sn1 reaction.
What happens to acceleration if both mass and force remian constant?
Since acceleration = force / mass, it will fall as mass increases.Progressive loss of mass is much more likely to occur in real life - for instance with a rocket, which burns fuel as it goes. In this case, acceleration will increase.
