Which image (A or B) shows the direction someone would need to kick the ball in order to move it toward the goal?

0

If the soccer ball is moving with a net force of 8 N towards the goal. How much force must the goalkeeper apply on the ball to stop it? What would happen if more or less force were applied by the goalkeeper?

Guided Notes: Energy

Newtons second law: acceleration of an object is dependent upon the force acting upon the object and the mass of the object.

F=MA

Step 1: write or rewrite the F=MA equation
Step 2: plug in the numbers into the equation
Step 3: solve the equation
Step 4: include the proper units and direction (force and acceleration)
