Study Notes
Force and Motion
- Force and motion are directly related, as a force is a push or pull that causes an object to change its motion.
- A force can cause an object to accelerate, decelerate, or change direction.
Unbalanced Force
- An unbalanced force is a force that is not opposed by an equal and opposite force.
- The effect of an unbalanced force on an object is to cause it to accelerate, or change its motion.
Force and Velocity
- Force is related to the velocity of an object, as a net force acting on an object will cause it to accelerate, resulting in a change in velocity.
- The greater the force, the greater the acceleration, and the greater the change in velocity.
