Physics Problem Set

Front

What is the formula to calculate the force required to accelerate an object?

Back

F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is the coefficient of friction?

Back

A measure of how much frictional force exists between two surfaces in contact.

Front

How do you calculate the tension in a cable supporting a mass at an angle?

Back

T = (mg) / (2 * cos(θ)), where m is mass, g is acceleration due to gravity, and θ is the angle.

Front

What does it mean for vectors to be perpendicular?

Back

Perpendicular vectors are independent of each other and do not affect each other's magnitude or direction.

Front

What is the condition for an object to be in equilibrium?

Back

The sum of all forces acting on the object must be zero.

Front

How do you calculate the net force acting on an object?

Back

Net force is the vector sum of all individual forces acting on the object.

Front

What is the relationship between mass and weight?

Back

Weight (W) is the force due to gravity acting on an object, calculated as W = m * g, where g is the acceleration due to gravity.

Front

What is the significance of a free body diagram (FBD)?

Back

A free body diagram visually represents all the forces acting on an object, helping to analyze the forces and motion.

Front

How do you find the acceleration of an object given the net force and mass?

Back

Use Newton's second law: a = F_net / m.

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed; it can only be transformed from one form to another.
