Newtown's Laws and Speed, Distance, and Time

How much force is needed to accelerate a 60 kg rider and her 240 kg motorcycle at 3 m/s²?

A bus took 12 minutes to drive 8 miles.  What was its average speed?

When a person jumps horizontally off of the end of an unanchored boat in a lake, the person goes forward and the boat goes backward. This is an example of what Law of Motion?

At what point is the object moving back to the starting point?

Match the description to the graph:

"The car is traveling at a constant speed, away from the reference point."

• 
• 
• 
• 

What is happening in this graph from point B to C?

• The object is going down a hill.
• The object is returning to its starting location.
• The object is slowing down.
• The object is staying still.

Two astronauts are playing catch in space. The first astronaut throws the ball; and

• the ball moves, but the astronaut doesn’t.

• the ball moves, and so does the astronaut.

• the ball doesn’t move, but the astronaut does.

• the ball doesn’t move, and neither does the astronaut.

A fireman turns on a hose and is knocked backwards

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

A force of 90N is applied to each cart below, which one will accelerate the fastest?

• Cart 1
• Cart 2
• Cart 3 
• Cart 4

How do you calculate time?

• multiply distance and speed

• distance divided by speed

• speed divided time

• divide distance and density then multiply by volume
