Kinematics of Linear Motion

The study of motion without regard to the forces that cause that motion is called

• kinematics

• kinetics

• mechanical advantage

• torque

The change in linear and angular position over time is known as

• acceleration

• position

• velocity

• power

How far an object has traveled from its starting point regardless of its starting or ending position.

• Distance

• Displacement

A measurement between the starting position and final position of an object.

• Distance

• Displacement

A golf ball accelerates off a tee at 15m/s², changing its velocity from 0m/s to 50 m/s down the fairway. How long did it take the golf ball to accelerate?

• 750 seconds

• 35 seconds

• 0.3 seconds

• 3.3 seconds

Which time interval shows a constant velocity and no acceleration?

• 18 s to 24 s

• 4 s to 18 s

• 0 s to 24 s

• 0 s to 3 s

If an object is moving with a positive velocity, a positive acceleration means that your object is

• at rest

• speeding up

• moving

• slowing down

What does kinematics focus on?

• The forces causing motion

• The way in which objects move

• The energy of moving objects

• The mass of objects
