Motion

An unbalanced force is when objects move in one direction because the force is greater from that direction.

• true

• false

Inertia is....

• for every action, there is an equal and opposite reaction

• larger objects take more force to move 

• an object in motion tends to stay in motion unless acted on by an opposite force

• a push that acts in the opposite direction and it slows down.

Which force produces a change in motion?

• unbalanced force

• balanced force

• gravitational force

• frictional force

An automobile you are riding in suddenly stops, why does your body continue to go forward?

• An object in motion stays in motion.

• Gravity pulls your body towards the earth.

• Friction makes your body slow down.

What is this?

"This airplane is traveling at 500 mph, West"

• Speed

• Velocity

• Acceleration

What is motion?

• the stopping of an object to a frame of reference

• a change in position relative to a frame of reference

• the middle ground between light and shadow, between science and superstition, and it lies between the pit of man's fears and the summit of his knowledge

• a change in the time in which it takes to get an office referral

Total distance divided by total time, for an object shows:

• acceleration

• the size of one's toupee

• absolute speed

• average speed

Investigate how the principles of motion and forces can be applied to design a new transportation system that minimizes environmental impact.

• Design a vehicle that uses renewable energy and test its efficiency in different terrains.

• Create a model of a traditional gasoline-powered vehicle and compare its efficiency to an electric vehicle.

• Build a rocket and measure how far it can travel using different fuels.

• Design a bicycle that uses solar power and test its speed on a flat surface.

How do you calculate distance?

• Distance divided by time.

• Displacement divided by time.

• Speed multiplied by time.

• Displacement divided by velocity.
