Acceleration of an object is caused by the application of a force to it. Heavier objects take more force to accelerate them.
Acceleration is measured by how many metres per second of speed is added every second, so it's in metres/second/second or metres per second2.
The force is related to the mass and acceleration by Newton's second law:
Force = mass x acceleration.
In this equation metric units can be used, with the force measured in Newtons, the mass in kilograms and the acceleration in metres/second2.
A 1-kg mass falling under gravity accelerates at 9.806 metres/second2 . This means that the gravity force, or weight, on a 1-kg mass is 9.806 Newtons.
Metric units don't have to be used, any other set of dynamical units can be used, for example mass can be in pounds, the force in poundals and the acceleration in ft/sec2. The weight of a 1-pound mass is 32.2 poundals.
If force is measured in pounds instead, the dynamical unit for mass is then the slug, and a 1-slug mass is a mass of 32.2 pounds.

Acceleration is caused by the presence of an unbalanced force acting on an object. This force can result from changes in the object's speed, direction, or both. Acceleration is directly proportional to the force applied and inversely proportional to the mass of the object.

Should acceleration be constant?
Acceleration is not necessarily constant; it can vary based on different factors such as changes in speed or direction. In scenarios where an object experiences a constant force, acceleration can be constant. However, factors like air resistance or changes in force can cause acceleration to change over time.
Why the acceleration of the cart decreases?
The acceleration of a cart can decrease due to various factors such as friction, air resistance, or an opposing force acting in the opposite direction. As these forces counteract the initial acceleration, they cause the cart to slow down and reduce its overall acceleration.
What 2 factors can cause a change in velocity?
Two factors that can cause a change in velocity are acceleration, which is the rate of change of velocity, and the application of an external force. An increase in acceleration will cause a greater change in velocity over time, while the direction and magnitude of an external force can also affect the velocity of an object.
What two factors depend on in acceleration?
Acceleration depends on two factors: the force applied to an object and the mass of the object. A greater force or a lower mass will result in a higher acceleration.
What factors can affect on acceleration?
Factors that can affect acceleration include the mass of an object (heavier objects accelerate more slowly), the force applied to the object (greater force leads to faster acceleration), and friction or air resistance (which can slow down acceleration). Additionally, the angle of incline or the surface on which the object is moving can also impact acceleration.

What 2 factors determine the shape of a snow crystal?
gravity and acceleration due to it or a friction in air which cause its uniform velocity

What are the two factors of acceleration?
Velocity and Time
On what two factors does acceleration?
It is velocity and distance. ----
What are the factors that reduce in case of friction?
the factors that reduce in case of friction are the velocity and acceleration.
Will leaving a force constant and doubling the mass of an object cause the acceleration to double?
Just the opposite. It will cause the acceleration to drop by 50%.
What factors can affect on acceleration?
Factors that can affect acceleration include the mass of an object (heavier objects accelerate more slowly), the force applied to the object (greater force leads to faster acceleration), and friction or air resistance (which can slow down acceleration). Additionally, the angle of incline or the surface on which the object is moving can also impact acceleration.
Does torque cause angular acceleration?
Yes.
Unbalanced forces on an object cause what?
