What is the formula statement of Newton's second law?
What is the equation relating an object's weight and the tension in the string suspending it if the object is at rest?
What is the equation relating an object's weight and the tension in the string suspending it if the object is moving either up or down at a constant velocity?
What is the equation relating an object's weight and the tension in the string suspending it if the object is moving upwards with a uniform acceleration?
What is the equation relating an object's weight and the tension in the string suspending it if the object is moving downward with a uniform acceleration?
What are the unit to measure gravitational field strength?
What are the units to measure mass?
What formula do you use to calculate the weight of an object?
What is the net force on a projectile in freefall at the apex of its trajectory?
On an inclined plane, what component of the object's weight accelerates it down the incline?
On an inclined plane, what component of the object's weight provides the force pressing it to the incline's surface?
An inclined plane is gradually raised, just at the instant that an object resting on it starts to slip the angle of inclination is measured. How can the value of this angle be used to calculate the coefficient of static friction between the object and the incline's surface?
If a more massive object made of the same material is placed on the same incline, will the angle in question #5 change?
What are the units used to measure the coefficient of friction between two surfaces?
formulae to calculate the components of the tension in a diagonal wire when q is measured from the vertical
What is the rule for tensions in ropes that meet at a knot?
What is the magnitude of the net force normal when an object is being pulled at a constant velocity across a rough horizontal surface by a cord with a tension T which makes an θ with the horizontal?
What is the magnitude of the friction present when an object is being pulled at a constant velocity across a rough horizontal surface by a cord with a tension T which makes an θ with the horizontal?
How should Newton's second law be stated when working problems in two dimensions?
True or False. Static friction is less than kinetic friction.
What is meant by recoil?
True or False. When two objects collide, the smaller mass receives the greater impact force.
True or False. Momentum is only conserved in elastic collisions.
How do you distinguish between elastic and inelastic collisions
