What is the speed and acceleration of a ball rolling down a hill?
The acceleration of a tennis ball rolling down an incline depends with two factors. The force that is applied to the tennis ball and the mass of the tennis ball will determine its acceleration.
What part of the graph represents uniform positive and negative acceleration Calculate this acceleration.?
The answer depends on whether the graph is that of speed v time or distance v time.
What do Newton's three laws state?
1. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied. 2. The relationship between an object's mass (m), it's acceleration (a), and the applied force (F) is F=ma. Acceleration and force are vectors; in this law the direction of the force vector is the same as the direction of the acceleration vector. 3. For every action there is an equal and opposite reaction.
How can you determine the amount of force exerted?
To find the force on an object, you multiple the mass of the object by its accelerationFor example, let's say a ball is moving at 7 m/s squared and has a mass of12 kg.The formula for force is: F = maF = 12 kg x 7 m/s squaredF = 84 N ( the unit for force is N, which is Newtons)*Be careful, an object does not "have a force". A force is an action that can modify the shape of an object and/or modify its velocity. Therefore, you do not calculate the force of an object, but the force required to give it a certain acceleration.
A table exerts a 4.0 kg Newton force on a book which lies at rest on its top The force exerted by the book on the table is?
An object travels in a circular path of radius 5.0 meters at a uniform speed of 10. m/s. What is the magnitude of the object's acceleration?
What are the equations of motion involving uniform acceleration?
The equations of motion involving uniform acceleration are: v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, t is the time taken. s = ut + (1/2)at^2, where s is the displacement. v^2 = u^2 + 2as, where s is the displacement. These equations describe the relationships between initial velocity, final velocity, acceleration, displacement, and time during motion with uniform acceleration.
If the displacement of a body is proportional to square of time will the body be moving with uniform velocity or uniform acceleration?
Let us suppose that the displacement is given by, x = kt2 , where k is constant of proportionality. Therefore, velocity of the body, v = dx/dt = d(kt2)/dt = 2kt Since, velocity depends on time ,the body is not moving with uniform velocity.... Again, acceleration of the body, a = dv/dt = d(2kt)/dt = 2k As the acceleration is independent of time , the body is moving with uniform acceleration..
Is centrifugal acceleration a uniform acceleration?
No, centrifugal acceleration is not a uniform acceleration. It is a type of acceleration that occurs when an object moves in a curved path and experiences an outward force away from the center of rotation. The magnitude of centrifugal acceleration changes as the object's speed or radius of rotation changes.
What is non uniform acceleration with an example?
Non-uniform acceleration occurs when an object's velocity changes unequally over time, resulting in a non-constant rate of acceleration. For example, a car that speeds up and slows down at different rates during a road trip experiences non-uniform acceleration.
What is the equation for uniform motion?
The equation for uniform motion is ( s = ut + \frac{1}{2}at^2 ), where ( s ) is the displacement, ( u ) is the initial velocity, ( a ) is the acceleration, and ( t ) is the time.
When will you say a body is in uniform acceleration non uniform acceleration?
Uniform (or constant) acceleration means that the acceleration doesn't change over time.
WHAT IS the example where acceleration is uniform?
Acceleration due to gravity is a uniform acceleration of 9.8m/s2.
How do you find the uniform acceleration if the speed and acceleration are given?
Find out the time using speed and acceleration, (time=speed/acceleration) and then use it to find out uniform velocity. From that find out uniform acceleration. (as uniform acceleration is equal changes of velocity over equal intervals of time)
For uniform circular motion the quantity that does not remain constant is?
this my sound rather daft but this is a bit of a trick question, the speed is the same so straight away you would think the acceleration is constant right....???? Wrong the displacement of the object is changing (displacement is the distance being travelled with a direction, a vector quantity.) as the displacement is changing so is the velocity, as velocity is displacement/time. as the velocity is changing so is the acceleration because acceleration is then change in velocity divided by time.
What is an example of non uniform acceleration?
An object moving in a circular path at a constant speed experiences non-uniform acceleration because its direction is constantly changing. This is because acceleration is a vector quantity that includes changes in both magnitude and direction.
What is uniform accelerating?
Uniform acceleration motion is a type of motion where the acceleration value is constant.
When will you say a body is in 1 uniform acceleration 2 non uniform acceleration?
Uniform acceleration means that the acceleration doesn't change over the course of time (of the time considered for a certain problem, at least).
