Force and Translational Dynamics
A car is moving at a constant velocity. What can you say about the forces acting on the car?
Which of the following is an example of an external force acting on a bicycle?
A person is pushing a box across a rough floor. Which of the following is NOT an external force acting on the box?
Two blocks are connected by a string. A force is applied to one block, pulling both blocks across a frictionless surface. What is the net external force on the system?
A 4 kg object experiences a net force of 20 N. What is its acceleration?
An object with a mass of 2 kg accelerates at 3 m/s². What is the net force acting on the object?
An object is subjected to two forces: 30 N to the right and 10 N to the left. If the object's acceleration is 4 m/s², what is its mass?
