Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A change to an objects motion is caused by ____
A
Balanced forces
B
unbalanced forces
C
Acceleration
D
Velocity
Explanation: 

Detailed explanation-1: -When the forces acting on an object are unbalanced, they do not cancel out one another. An unbalanced force acting on an object results in the object’s motion changing. The object may change its speed (speed up or slow down), or it may change its direction.

Detailed explanation-2: -Unbalanced forces can cause an object to change its motion. If an object is at rest and an unbalanced force pushes or pulls the object, it will move. Unbalanced forces can also change the speed or direction of an object that is already in motion.

Detailed explanation-3: -Change to an object’s motion is caused by unbalanced forces, including Earth’s gravitational attraction, acting on the object.

Detailed explanation-4: -Students understand that unbalanced forces affect motion of objects by causing them to accelerate, decelerate or change direction.

Detailed explanation-5: -If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced. An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.
