A 1-kg mass at Earth's surface weighs about

2000 N

A car has a mass of 1000 kg and accelerates at 2 m/s2. What is the magnitude of the force exerted on the car?

A man weighing 800 N stands at rest on 2 bathroom scales so that one scale shows a reading of 500 N. The reading on the other scale is

According to Galileo, inertia is a

30 N to the right

An object is pulled with 3 forces: one at 20 N to the right, another at 40 N to the right, and the third at 30 N to the left. The net force is

Newton's 2nd law directly involves

5 N east

When a 10-kg block is simultaneously pushed toward the east with 20 N and toward the west with 15 N, the combination of these forces on the block is

Whenever the net force on an object is zero, its acceleration
