gr 10 introduction

Centripetal force, created by swinging something in a circle, acts in a direction--

• along the path of motion

• away from the center of the circle

• toward the center of the circle

• tangent to the circle

_________ moving or tending to move toward a center.

• centripetal force

• centrifugal force

• speed

• velocity

Which of the following is the unit for centripetal force?

• J
• m/s²
• kg⋅m/s
• N

Ideal fluid has

• Static condition

• Zero viscosity

• constant viscosity

• incompressible nature

The upward force exerted by a fluid on a submerged object.

• gravity
• anti-gravity
• buoyant force
• lift

The rule that when force is applied to a confined fluid, the increase in pressure is transmitted equally throughout.

• pascal's principle
• bernoulli's principle
• archimedes' principle
• Newton's Law

A system that multiplies force by transmitting pressure from a small surface area through a confined fluid to a larger surface area.

• hydraulic system
• archimedes system
• pressure system
• bernoulli effect

What is the equation for pressure?

• Pressure = Force / Surface area
• Pressure = Force x Surface area
• Pressure = Force + Surface area
