The diagrams below show different objects of equal masses that are acted on by one or more forces. In the diagrams below, each force vector labeled F has the same magnitude. (a)Which of the four objects shown has a net zero force acting on it?(i)(ii)    (iii)(iv)(b)Which object or objects have the largest magnitude of force? (Select all that apply.)(i)(ii)(iii)(iv)(c)Which object or objects move with constant velocity? (Select all that apply.)(i)(ii)(iii)(iv)(d)Which object or objects move with changing speed? (Select all that apply.)(i)(ii)(iii)(iv)

The table below shows the mass and acceleration of four objects. Object Mass (kg) Acceleration (m/s2) Q  6  20 R  3  32 S  13  11 T  5  29Which object is experiencing the greatest force?A QB RC SD T

Two forces A and B act on an object in opposite directions. A is bigger than B. The net force on the object is:

Three vector forces F1, F2 and F3 act on aparticle of mass m = 3.80 kg as shown in Fig.• (i) Calculate the magnitude and direction ofthe net force acting on the particle.• (ii) Calculate the particle’s acceleration.• (iii) If an additional stabilizing force F4 isapplied to create an equilibrium conditionwith a resultant net force of zero, what wouldbe the magnitude and direction of F4?

The same resultant force acts on objects 1 and 2. Object 1 accelerates at 2m/s² and Object 2 accelerates at 5m/s². Which object has the greater mass?

Four forces are acting on a body. If the body doesn’t change its position or shape, the forces:(A) must be of equal magnitude(B) must be parallel & opposite(C) must add up to zero when taken as vectors(D) must be in a single line
