What is the motion of a freely faling body?
A freely falling body undergoes uniform acceleration due to gravity, moving in a straight line towards the Earth's center. The acceleration experienced by the body is approximately 9.8 m/s^2 near the Earth's surface.
An object has initial velocity in the upward direction a final velocity in the downward direction and undergoes constant acceleration What can you say about its average acceleration?
The average acceleration of the object will be negative since it changes direction from upward to downward velocity. The acceleration will be constant because the object undergoes constant acceleration throughout the motion.
When an object undergoes an acceleration?
when it is acted on by a force
What happens when centripetal acceleration occurs?
When centripetal acceleration occurs, it causes an object to move in a circular path by continuously changing the direction of its velocity. This acceleration is always directed towards the center of the circle and is necessary to balance the outward centrifugal force, keeping the object in its circular motion.
If a body is acted by a constant force the body will have uniform?
"acceleration"
When a body undergoes an acceleration does its speed increase or decrease?
Both. Acceleration is a change in speed.
When do you have motion?
When an unbalanced force act on a stationary body, it undergoes an acceleration in velocity and thus motion is produced

What happens to an object when it undergoes acceleration is it the speed or velocity that increases?
When an object undergoes acceleration, it is the velocity that increases. Acceleration is the rate of change of velocity, so an object experiencing acceleration will have its velocity change over time, either by speeding up, slowing down, or changing direction.
When an object undergoes an acceleration?
when it is acted on by a force
When does an object undergoes acceleration?
Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...Thus...An object undergoes acceleration when:1. there is a change in the magnitude of the velocity (speed) of an object.2. there is a change in direction of an object.3. it changes both in direction and magnitude.
What is newtons2nd law?
When unbalanced forces acts on a body , the body undergoes accelerationin the direction of the net force.F = maWhere F = vector sum of all forces acting on the objectm = mass of the objecta = vector acceleration of the object

Is motion of swing an example of simple harmonic motion?
A body undergoes simple harmonic motion if the acceleration of the particle is proportional to the displacement of the particle from the mean position and the acceleration is always directed towards that mean. Provided the amplitude is small, a swing is an example of simple harmonic motion.
When a body has velocity no constant has acceleration or no?
Yes. If a body has a constant velocity there is no acceleration, but if the velocity is changing there is acceleration present.
