Use the drop-down menus to complete each sentence. The force applied to the physics cart is manipulated. This is the variable. The cart accelerates due to the force applied to the cart. Acceleration is therefore the variable. A “constant” is a parameter that stays the same regardless of the variables. One parameter of the cart that is held constant is the .

Avalue that describes how heavy an object is and is related to the force of gravity is

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?

Which sentences describe point source pollution? in this type of pollution, the source of the pollution is single and easily identifiable. when runoff water from the melting of snow mixes with debris, it creates pollution. the runoff water, mixed with pollutants, reaches large areas with disastrous effects. alternatively, when a wastewater treatment plant releases harmful chemicals into a stream, the chemicals pollute the stream water because they are not treated for safety.
