Review of Forces (in SPH3U)

What is the standard unit of force in the Metric system?

The diagram on the right is called a:

The order, from strongest to weakest, for the 4 fundamental forces is: ("e/m"= electromagnetic)

Which is not a real, specific force?

Which is NOT something that friction and normal force have in common?

The diagram on the left is called a:

Net Force (F_net) is not the same as:

What force is responsible for holding the nucleus of an atom together?

If a mass is simply hanging on a string, at rest, which force acts upward on the mass?

How much stronger is the strong nuclear force than the force of gravity?

If you want to accelerate a 2000 kg car at 1.5 m/s/s for 3 s, how much net force will you need?

What type of contact force can result in a pull along its line of action, in any direction (on Earth)?

Force is the *** for any change in motion.

What is the standard unit of weight in the Metric system?

The net acceleration for a 20 kg mass subject to the forces in this picture is:

What force acts along a line of contact between 2 surfaces, opposing motion or any attempt at motion?

A 1600 kg mass has a braking force of 19 200 N. The brakes slow it down at which rate of a?

The electromagnetic force includes all of these, except for:

Which force prevents you from falling through your chair as you sit on it?

The net force in this picture is:

Which force always results from 2 surfaces pressing each other while in contact?

Which of these is not a fundamental force?

'Weight' is symbolized by:
