Scalar - Answer quantities with only magnitude such as speed, distance, time and mass. Vector - Answer quantities with a magnitude and direction e.g. acceleration, force momentum and weight. A vector quantity can be represented as an arrow, the size representing the magnitude and the direction, the direction. Non-contact force - Answer the objects are physically separate e.g. magnetism/gravity/electrostatic. 3 non-contact forces - Answer magnetism gravity electrostati...

Honors Physics Final Exam Questions and Answers Graded A+ What is the principle of inertia? The principle of inertia states that an object will not change its state of motion unless acted upon by an external force. How does friction affect the motion of an object? Friction opposes the motion of an object, causing it to slow down or stop. What is the concept of momentum? Momentum is the quantity of motion an object has, which depends on its mass and velocity. What is the dif...

Scalar - ANS-quantities with only magnitude such as speed, distance, time and mass. Vector - ANS-quantities with a magnitude and direction e.g. acceleration, force momentum and weight. A vector quantity can be represented as an arrow, the size representing the magnitude and the direction, the direction.

Physics Test Question and answers already passed Physics Test What is the net force on a box pushed to the right with 50 N of force while being pushed to the left with 20 N of force? - correct answer The net force is 30N to the right What two quantities are necessary for a vector quantity? - correct answer direction and magnitude An object is at rest. The forces acting on the object - correct answer are opposite in direction, are equal in magnitude, and have a vector sum of ze...
