9thA Newton's Law

Speed involves two quantities:

• distance and time

• time and direction

• direction and distance

• velocity and distance

When one object applies a force to a second object, the second object applies an equal and opposite force to the first object.

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

• Newton's Fourth Law

is a change in an object's position over time

• Speed

• Motion

• Object

• Reference Point

What term describes the process of comparing an object's position to that of another object, which seems to remain stationary throughout the comparison?

is a measure of the distance an object moves in a given amount of time.

• Distance

• Time

• Speed

• Gravity

A car travels 100 kilometers in 2 hours. What is its average speed?

Unless acted on by an unbalanced force, an object at rest stays at rest and an object in motion stays in motion at a constant velocity.

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

• Newton's Fourth Law

A train travels at a constant speed of 80 kilometers per hour. How far will it travel in 2.5 hours?

• 100 kilometers

• 150 kilometers

• 200 kilometers

• 250 kilometers

is a quantity that describes the speed of the object and its direction of travel.

• Speed

• Velocity

• Time

When the cart is loaded, it has ___________________mass than when the cart is empty. The boy must apply ______________________force to the loaded cart for its acceleration to be the same as when it is empty.

• more, more

• less, more

• more, less

• less, less
