Force and Motion 1

What 2 things does speed depend on?

• distance and friction
• velocity and time
• velocity and friction
• distance and time

Which example shows NO acceleration?

• going straight at a constant speed
• going straight while slowing down
• speeding up
• circling at at constant speed

Which describes velocity?

• Speed with direction
• The same thing as speed
• how fast something is moving

What is the net force on the block? (click on the words to view the picture)

• 5 Newtons up
• 5 Newtons down
• 15 Newtons up
• 15 Newtons down

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 inertia?

• the tendency of an object to resist change in motion
• how fact an object is going in a given direction
• a measure of the lack of motion of an object
• change in speed or direction of an object

which is the unit of measure for acceleration?

• m/s
• mph
• m/s²
• km/h

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
