PS 2.2 & 2.3 - velocity, momentum, acceleration

The correct equation to calculate speed is

• distance divided by time
• time divided by distance
• distance x time
• distance divided by distance²

You walk 10 meters to math class in 20 seconds. Your average speed is

• 2 m/s
• 0.5 m/s
• 200 m/s
• 5 m/s

What is velocity?

• the quickness of an object
• the location of an object
• acceleration
• speed in a specific direction

What is acceleration?

• Change in speed
• Change in direction
• Change in velocity
• Change in mass

Acceleration is....

• Speeding up only

• Speeding up and slowing down

• Slowing down only

• Any change in speed (faster or slower) or a change in direction.

Jose wandered 4 km at 2 km/hr. How long did Jose wander?

• 2 hours

• 8 hours

• 0.5 hours

• 2 km

65 miles per hour North is an example of an objects what?

• Speed
  
• Velocity
• Average Speed
• Constant Speed

Momentum is...

• rolling down a hill.

• the amount of motion an object has.

• the force that an object has.

• the speed of an object.

The equation for momentum is?

• momentum = force - mass

• momentum = acceleration / mass

• momentum = mass x acceleration

• momentum = mass x velocity

What is true about the relationship between mass and momentum.

• The less mass an object has, the more momentum it will have.

• The more mass an object has, the less momentum it will have.

• The more mass an object has, the more momentum it will have.

• Mass has nothing to do with momentum.
