When a force is applied to an object, it can cause the object to accelerate, move, deform, or change its shape. The specific changes that occur depend on factors such as the magnitude and direction of the force, as well as the properties of the object, such as its mass or elasticity.

When and why does the speed of an object change with time?
The speed of an object changes with time when there is an external force acting on it, causing acceleration. This change in speed can occur when the object is accelerating or decelerating due to forces like gravity, friction, or applied thrust.
A constant force of 4.0 N acts on a variety of objects. The greatest acceleration will occur in the object that has?
The greatest acceleration will occur in the object with the smallest mass. This is because acceleration is inversely proportional to mass when a constant force is applied (F = ma). The object with the smallest mass will experience the greatest acceleration when the same force is applied.
Does a change in motion occur only if a net force is exerted on an object?
Yes, according to Newton's first law of motion, an object will remain at rest or continue moving at a constant velocity unless acted upon by a net force. When a net force is applied to an object, it will experience a change in motion.
What are the ways in which a force can change the motion of body?
A force can change the motion of a body by causing it to speed up, slow down, change direction, or deform. These changes occur due to the interaction between the force applied and the mass and geometry of the object.
What must occur for work to be done?
For work to be done, a force must be applied to an object, causing it to move in the direction of the force. Work is defined as force acting over a distance, so the object must be displaced by the force applied to it in order for work to be done.
When does acceleraion occur?
Acceleration occurs when there is unbalanced force applied to an object.

What must occur for work to be done?
For work to be done, a force must be applied to an object, causing it to move in the direction of the force. Work is defined as force acting over a distance, so the object must be displaced by the force applied to it in order for work to be done.
A second force of 13 N is applied to the object. If this second force is applied toward the left while the first force is being applied toward the right which of the following will occur?
The object will experience a net force of 7 N to the right (20 N - 13 N), causing it to accelerate in that direction.
When velocity may change?
Velocity may change when an object experiences a change in speed or direction. This can occur when a force is applied to the object, causing it to accelerate or decelerate. Changes in velocity can also happen if an external force opposes or alters the object's motion.
For motion to occur?
For motion to occur, an object must experience a force that causes it to accelerate and move. This force can come from sources like gravity, friction, or applied forces. In the absence of a force, an object will remain stationary or in constant motion.
Why will momentum change?
Momentum will change if there is a force acting on an object. This change in momentum can occur due to accelerations, decelerations, changes in direction, or interactions with other objects. The magnitude and direction of the momentum change depend on the strength and direction of the force applied.
When does an object stop?
An object stops when the forces acting on it result in a net force of zero, causing it to reach a state of equilibrium. This can occur when the forces are balanced, such as when the force of friction is equal and opposite to the applied force.
In order for work to be done explain the two things that must occur?
In order for work to be done, a force must be applied to an object, causing the object to move, translating the force into displacement. Work is calculated as the force applied multiplied by the distance the object moves in the direction of the force.
