Force and Motion Review

What is velocity?

• A measure of how fast something moves between 2 points
• A measure of both the speed and direction of a moving object
• a force that considers the rate at which acceleration changes
• a force that opposes motion between 2 surfaces that are touching

How do you know an object is in motion?

• It is touching another object
• By its velocity
• Because it  is changing positions
• Gravity is keeping it on the ground

What can the angry bird do to travel the farthest distance possible?

• Switch with a heavier bird and pull back a shorter distance
• Switch with a heavier bird and pull back a farther distance 
• Switch with a lighter bird and pull back a shorter distance
• Switch with a lighter bird  and pull back a farther distance

This boy is rolling down a hill at a constant speed.  What is changing as the boy rolls?

• velocity
• speed
• acceleration
• position

What is the best way to test friction?

• Drop a ball from different heights
• Use a spring scale to lift several blocks
• Use a balance to find the mass of an object
• Roll a toy car across different surfaces

What science topic must a civil engineer understand before she designs a structure?

• electricity
• plants
• forces
• geography

The graph shows the relationship between distance and time of a moving object.  What was the car doing between points B and C?

• It accelerated
• It stopped moving
• It slowed down
• It was put on a steep incline

What is the difference between speed and velocity?

• gravity
• acceleration
• motion
• direction

An object moves from Point a to Point B in 2 minutes at a constant rate.  Point A is 22 meters from Point B.  What is the speed of the object?

• 11 m/min
• 22 m/sec
• 44 m/sec
• 11 sec/m

Which of the following is an example of a force?

• Speed
• Push
• Motion
• Velocity
