A spring has a natural length of 4 cm and when masses are added, its new length is 18 cm. What is the extension?

14 cm

How do you calculate average speed?

total distance divided by total time

What is the resultant force?

0 N

Dave runs 2000 m in 25 minutes. What is the speed?

80 m/m

The mass of an astronaut is 70 kg on the Moon. What is the mass of the astronaut on the Earth?

70 kgs

A spring has a spring constant of 5 N/cm. What is its extension when loaded with 15 N?

3 cm

A golf ball accelerates off a tee at 15m/s2, changing its velocity from 0m/s to 50 m/s down the fairway. How long did it take the golf ball to accelerate?

3.3 seconds

A dog runs with an initial speed of 7.5 m/s on a waxed floor. It slides to a stop in 15 seconds. What is the acceleration?

40 N, right

What is the resultant force?

None

TRUE OR FALSE: To represent a force, you can use either the point of application (where the force acts), scalar value, and the direction.

TRUE.

Change in speed or velocity over a specific amount of time. What is this?

Acceleration
