### Ch. 3 Motion & Forces

Jeopardy Review

Round 1

Round 2

Need for Speed – 10 points
• Scientific unit for speed
• m/s

Next Question

Need for Speed – 20 points
• The two factors that determine speed.
• Distance & time

Next Question

Need for Speed – 30 points
• Speed in a particular direction.
• Velocity

Next Question

Need for Speed – 40 points
• Formula for calculating average speed.
• Distance traveled divided by time it took (d/t)

Next Question

Need for Speed– 50 points
• The factor placed on the y-axis when graphing speed.
• Distance [time is on the x-axis]

Next Question

The Force Be With You – 10 points
• Forces that cause no change in speed or direction.
• Balanced

Next Question

The Force Be With You – 20 points
• Forces that cause a change in speed, direction, or both.
• Unbalanced

Next Question

The Force Be With You – 30 points
• The scientific unit of force.
• Newton

Next Question

The Force Be With You – 40 points
• The combination of all the forces acting on an object.
• Net force

Next Question

The Force Be With You – 50 points
• The net force on a rope when one dog pulls with a force of 20 N east and another dog pulls with a force of 12 N west.
• 8 N east

Next Question

Rub A Dub Dub – 10 points
• A force that opposes motion between two surfaces that are in contact.
• Friction

Next Question

Rub A Dub Dub – 20 points
• Name 2 types of friction that can occur due to motion of one or more objects.
• Sliding, rolling, fluid friction (these are all examples of kinetic friction)

Next Question

Rub A Dub Dub – 30 points
• Friction that occurs between two objects that are not moving.
• Static Friction

Next Question

Rub A Dub Dub – 40 points
• State one way you could decrease friction in a car’s engine.
• Lubricant—oil, grease

Next Question

Rub A Dub Dub – 50 points
• The two factors that determine how much friction exists between two objects.
• Force (how hard you push) & Roughness of the surfaces

Next Question

A Matter of Gravity – 10 points
• A measure of the force of gravity on an object.
• Weight

Next Question

A Matter of Gravity – 20 points
• The scientific unit used to measure weight.
• Newton (a measure of a force—gravity!)

Next Question

A Matter of Gravity – 30 points
• Gravity ___________as distance between two objects increases.
• Decreases

Next Question

A Matter of Gravity– 40 points
• Calculate the acceleration of a roller coaster that goes from a speed of 0 m/s to 8 m/s in 8 seconds.
• 1 m/s2

Show Work: [8m/s – 0m/s]/8 s= 1 m/s2

Next Question

A Matter of Gravity– 50 points
• Gravity ____________as the mass of the objects increases.
• Increases

Next Question

Newton Rules – 10 points
• The force that causes the speed of a falling object to slow down.
• Air resistance

Next Question

Newton Rules – 20 points
• Assuming no air resistance, which will hit the ground first: a shot put or a soft ball dropped at the same time from the top of the school building?
• They will hit at the same time.

Next Question

Newton Rules– 30 points
• When force increases, acceleration ___________.
• Increases

Next Question

Newton Rules – 40 points
• When mass increases, acceleration _____________.
• decreases

Next Question

Newton Rules– 50 points
• The tendency of an object to remain “as is” (whether at rest or in motion).
• Inertia

Next Question
