Force and Motion

How is gravity affected by mass?

• the larger the mass of the object, the greater the gravity
• small objects have no gravity
• gravity is not affected by mass of objects, whether large or small

which force produces a change in motion?

• unbalanced force
• balanced force
• gravitational force
• frictional force

What is a force that opposes motion between two surfaces?

• friction
• acceleration
• velocity
• motion

What is the difference between mass and weight?

• mass is how much matter is in an object, and weight is the gravitational pull on that object
• mass and weight are the same
• weight affects how much mass is in an object
• weight is determined by how many atoms make up an object

Find the average speed of a train that traveled 540 km in 6 hours?

• 80 km/h
• 100 km/h
• 90 kn/h
• 3240 km/h

The picture of the position vs. time graph shows an object that is...

• accelerating/speeding up
• moving at a constant speed 
• not moving 
• accelerating/slowing down. 

If these boys are pulling with the same amount of force.  What will happen?

• The boy in blue will win.
• They will not move at all.
• The boy in red will win.
• Both will fall down.

What is the location of an object?

• point
• position
• the sun
• intertia

When you tell the direction and speed of an object, you give its

• motion
• velocity
• acceleration
• mass

A train is traveling at a speed of 75 mph. Suddenly, it starts going faster. What caused the increase in speed?

• velocity
• inertia
• a force
• gravitation
