What has a higher acceleration a 10-kg object acted upon with a net force of 20 N or an 18-kg object acted on by a net force of 30 N?

Acceleration = (force)/(mass)
For the first object, A = 20/10 = 2 m/s2
For the second object, A = 30/18 = 12/3 m/s2
The acceleration of the first object is 20% greater
than the acceleration of the second one.

How does net force affect acceleration?
If net force acting on a mass decreases, the acceleration of the object decreases. But if the mass of an object were to decrease while a constant net force acted on it, its acceleration would INcrease. If the net force on the object AND the object's mass both decrease, the object's acceleration could either increase OR decrease. We'd need the actual numbers in order to calculate how it would turn out.
What two factors does acceleration depend on?
-- the magnitude and direction of the force acting on an object -- the mass of the object being forcefully acted upon
What is the law of Newton first law?
which are vectors? force, momentum, time, acceleration, distance.
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 does newtons first law of motion state about objects at rest and objects in motion?
An object in motion will not change its motion unless acted on by an external force. This applies to zero motion also.
When an object undergoes an acceleration?
when it is acted on by a force
What happen if an object is acted upon by balanced forces?
In this case, it is as if no force acted on the object. The object won't acceleration; if it is resting, it will continue resting, and if it is moving, it will continue moving at the same velocity.
What occurs to an object's direction when acted on by an unbalanced force?
Direction will be changed by the force caused acceleration, a=F/m.
How are Force Acceleration and Mass related?
(Force on an object) = (the object's mass) times (its acceleration)
What can cause the velocity of an object to change?
Acceleration is a change in the speed of an object (contrary to popular belief - acceleration ban be an increase or decrease in speed). Velocity of an object only changes when acted on by an external force like a push, friction or other force. Objects in motion stay in motion until acted on by an external force
How does net force affect acceleration?
If net force acting on a mass decreases, the acceleration of the object decreases. But if the mass of an object were to decrease while a constant net force acted on it, its acceleration would INcrease. If the net force on the object AND the object's mass both decrease, the object's acceleration could either increase OR decrease. We'd need the actual numbers in order to calculate how it would turn out.
What is the relationship between force and speed?
Speed is often used to mean velocity but force relates to acceleration. Newton's Second Law states that force equals mass times acceleration. F = ma The higher the force applied to an object the greater will be its acceleration. When the force is no longer applied the object continues at that velocity (speed) until acted on by an external force (which will decelerate it) External forces include wind resistance, friction, gravity.
Difference between gravity and upthrust?
Thrust is the quantity of force acted by a type of engine on an object which results in acceleration.
Why is force larger when objects are thrown from higher distance?
Force equals mass times acceleration (F=ma) . If an object is at a higher hight, it has more time to acceleration.
What happens when force is decreased?
Assuming that mass stays constant, a decrease in force will result in a corresponding decrease in the acceleration of the object being acted upon by the force.
Will acceleration of an object affect the force?
Remember Newton's First Law - Unless acted on by a force, bodies at rest will stay at rest and bodies in motion will stay in motion. To be able to observe acceleration, first a force has to act on the object. So, the question should be reversed - "Will the force on an object affect the acceleration?" Answer - YES. How will it be affected? Refer to Newton's Second Law for that.
What two factors does acceleration depend on?
-- the magnitude and direction of the force acting on an object -- the mass of the object being forcefully acted upon
