Physics

Standard PS-5:   The student will demonstrate an understanding of the nature of forces and motion.

 

Indicators

Activities

PS-5.1    Explain the relationship among distance, time, direction, and the velocity of an object.

 

PS-5.2    Use the formula v = d/t to solve problems related to average speed or velocity.

 

PS-5.3    Explain how changes in velocity and time affect the acceleration of an object.

 

PS-5.4    Use the formula a = (vf-vi)/t to determine the acceleration of an object.

 

PS-5.5    Explain how acceleration due to gravity affects the velocity of an object as it falls.

 

PS-5.6    Represent the linear motion of objects on distance-time graphs.

 

PS-5.7    Explain the motion of objects on the basis of Newton’s three laws of motion: inertia; the relationship among force, mass, and acceleration; and action and reaction forces.

 

PS-5.8    Use the formula F = ma to solve problems related to force.

 

PS-5.9    Explain the relationship between mass and weight by using the formula FW = mag.

 

PS-5.10  Explain how the gravitational force between two objects is affected by the mass of each object and the distance between them.
