Across.1. One manifestation of energy, which is defined as the product of the force and the distance moved by its point of application along the line of action of the force. 2. Any action that alters or tends to alter a body’s state of rest or of uniform motion in a straight line. 5. The capacity of an object for doing work. 6. A force which is equal to the gravitational force acting on a body on a horizontal surface, when the vertical component of the body’s acceleration is equal to zero 7. Of a constant force F, the product, Ft, of the force and the time t for which it acts. 9. The product of the mass and the velocity of the particle. 10. Physical quantity, a measure of resistance of a body to changes in its motion.

Down. 1.A condition obtained in free fall when reaction is absent. 3. SI unit of force. 4. The property of a body, proportional to its mass, which opposes a change in the motion of the body. 8. The rate at which energy is expended or work is done.
