One is when a force is applied. Two is exposure to a gravitational field which causes an acceleration due to the object approaching the center of gravity. Both of these apply to deceleration as well which is still acceleration. For instance a ball thrown into the air will decelerate to a stop or a curving arc. but this is still acceleration.
-Reduce the object's mass.
-Increase the force applied to the object
a = F/m Make the numerator larger (apply more force), or the denominator smaller (reduce the mass of the object).

Two or more forces that act on an object that do not cancel each other?
If the sum of all forces acting upon an object is not zero, then the object will accelerate. (Newton's first law)
What must be applied to an object to change its motion or direction?
If an object is at rest, a force must be applied to accelerate it (start it moving).
When two forces acting on an object are equal?
Newton's first law states that an object at rest stays at rest and an object in motion stays in motion with constant velocity unless acted upon by an unbalanced force. This is also called the law of inertia. So, the forces acting on an object are balanced when the object is not accelerating. This happens when the object is at rest, or when the object is moving at constant velocity. ===================== The forces on an object are balanced when their vector sum is zero.
What is the definition of a unbalanced force?
There is no such thing as "an unbalanced force". There are only forces. When two or more separate forces act on the same object, the GROUP of forces may be balanced or unbalanced. If the sizes and directions of all the individual forces add up to zero, then the GROUP of forces is balanced. If one of them changes or goes away, then the GROUP of forces is unbalanced.

What are two ways that an object can accelerate?
An object can accelerate by speeding up (increasing velocity) or by changing direction (experiencing a change in acceleration).
When two forces act in opposite directions the object will accelerate in the same direction as the what?
The object will accelerate in the same direction as the larger force.
If a constant force acts on two object's of different masses which object will accelerate more?
The object with a smaller mass will accelerate more when acted upon by a constant force because acceleration is inversely proportional to mass. Specifically, the acceleration is calculated by dividing the force by the mass of the object, so a smaller mass will result in a greater acceleration.
What are two ways to increase the acceleration in an object?
To increase acceleration in an object, you can either increase the force acting on the object or decrease the object's mass. Increasing the force will lead to a greater acceleration according to Newton's second law (F=ma), while reducing the mass will result in the object being easier to accelerate.
What are the two ways that a roller coaster can accelerate?
Slowing down and Speeding up
How is motion of an object affected when force acts on it?
If a force is exerted on an object, it will accelerate in inverse proportion to its mass in the direction of the force. For example, if two objects of different mass are subjected to the same force, the less massive object will accelerate more.
When two unequal forces act in opposite directions on a moving object what will the object do?
The object will accelerate in the direction of the larger force. The net force acting on the object is the difference between the two forces, causing the object to move in the direction of the larger force.
What are the two ways to measure the density of an object?
The two ways to measure the density of an object are by using its mass and volume. You can calculate density by dividing the object's mass by its volume, or by measuring the displacement of water when the object is submerged in it.
How growth in the GDP may impact negatively on the standard of living of a country?
two ways in which growth in a country's gross domestic product may negatively impact the country's standard of living
What are two ways an object can move?
back and forth?
Why we need a net force to determine an object's motion?
At any moment, several forces may act on an object. If, for example, two forces of the same magnitude act in the opposite directions, they cancel each other. To accelerate an object, a net force, or total force, different from zero, is required.
Two or more forces that act on an object that do not cancel each other?
If the sum of all forces acting upon an object is not zero, then the object will accelerate. (Newton's first law)
