What else can I help you with?
When a force is applied to an object it?
causes the object to accelerate or change its motion. The direction and magnitude of the force determine how the object will move. The force can cause the object to speed up, slow down, or change direction.
What happensto the speed of an object if a unbalanced force acts on it?
Then the speed will change.Then the speed will change.Then the speed will change.Then the speed will change.
Describe a situation in which gravity causes a change in velocity why does a change in velocity happen?
When an object is dropped from a height, gravity causes it to accelerate towards the ground. This acceleration leads to a change in velocity as the object's speed increases. The change in velocity occurs because gravity exerts a force on the object, pulling it towards the Earth.
If the speed of an object does NOT change the object is traveling at a what?
It is travelling at a constant speed. This does not mean that there is no acceleration or that the direction of motion remains the same.
Does change in speed of an object always indicate a change in speed?
Yes, a change in speed of an object always indicates a change in speed. Speed is a scalar quantity that represents how fast an object is moving without specifying the direction, so any change in the speed of an object indicates that it is either speeding up or slowing down.
Anything that causes and object to move or change its speed or change its direction is called what?
A force.
What causes an object to slowdown or speed- up?
An object can only slow down, speed up, or change direction, if there is a net force acting on the object.
Can A force can cause an object to change its speed?
Yes,because if a force is getting weaker it causes the speed to slow down but if the force is getting stronger it causes the object to move faster.
How do forces cause an object to change its speed?
A forces on an object m creates an acceleration a=f/m and acceleration causes a change in velocity a= dv/dt. This change in velocity can change the speed or direction or both.
What is needed to cause the object at rest to move or an object in motion to change the direction or speed?
Force, which causes acceleration
Which of these would change the direction of an object but not affect the object's speed?
Changing an object's direction without affecting speed requires a force that acts perpendicular to the object's velocity, such as centripetal force or gravitational force. This force causes the object to change direction while continuing at a constant speed. Other forces acting parallel to the object's velocity can change its speed as well as its direction.
When a force is applied to an object it?
causes the object to accelerate or change its motion. The direction and magnitude of the force determine how the object will move. The force can cause the object to speed up, slow down, or change direction.
What causes an object to change speed of the direction of motion?
A force acting on the body, along its line of motion.
What happensto the speed of an object if a unbalanced force acts on it?
Then the speed will change.Then the speed will change.Then the speed will change.Then the speed will change.

It is travelling at a constant speed. This does not mean that there is no acceleration or that the direction of motion remains the same.
What causes an object to change speed or thw direction of motion?
Any net non-zero force acting on it.
