Forces

How far something moves at a given time

• Velocity
• Motion
• Speed
• Acceleration

Speed and velocity are measured in...

• distance per unit motion
• distance per unit position
• distance traveled divided by time taken to travel
• distance per unit of time

Katie uses all her force to push a bowling ball and then a soccer ball. How does the movement of both balls differ?

• Bowling ball will move farther since it has more mass
• bowling ball will move farther since it has less mass
• soccer ball will move farther since it has less mass
• soccer ball will move shorter since it has less mass

What is force measured in?

• Issacs
• Newtons
• Mass
• decimals

Which surface will friction be greatest on?

• carpet
• grass
• gravel
• tile

What is acceleration?

• how much the velocity of an object changes in a certain time 
• how much the time changes based on velocity of an object
• the opposite of velocity
• how far something moves at a given time

Inertia is...

• resistance to a change in mass
• resistance to a change in velocity
• resistance to a change in motion
• resistance to a change in speed

Gravity is dependent on two things...

• mass and speed
• force and distance
• distance and mass
• force and speed

What do you use to measure force?

• weight scale
• spring scale
• cylinder
• ruler

A claw is lifting a stuffed animal from the crane machine, what force is the claw working against to lift the stuffed animal?

• wind
• friction
• gravity
• cable tension
