Motion Test Flashcards
The main forces that affect the motion of everyday objects include:
- Gravity
- Friction
- Inertia
- All of the above
A= All of the above
Acceleration always refers to a:
- Change in mass
- Change in speed
- Change in direction
- Change in velocity
A=Change in speed
Without an unbalanced force acting on it, a moving object will:
- Keep moving
- Maintain a constant speed
- Keep going in the same direction
- All of the above
A=All of the above
Factors that affect the acceleration of an object include the:
- Object’s speed and mass
- Object’s mass and weight
- Object’s friction force
A=Object’s speed and mass
Which equation shows the correct equation for determining acceleration:
- Acceleration = net force X mass
- Acceleration = net force / time
- Acceleration = (final speed - initial speed) / time
- Acceleration = mass / speed
A= Acceleration = (final speed - initial speed) / time
The tendency of an object to resist motion is called:
- Gravity
- Velocity
- Inertia
- Force
A=Inertia
The reaction to an action is always:
- Equal and opposite
- Equal and in the same direction
- Unequal and opposite
- Unequal and in the same direction
A=Equal and opposite
Which equation shows the correct calculation for force:
- Force= Mass / Acceleration
- Force= Mass X Acceleration
- Force= (final speed - initial speed) / time
- Force= Speed / distance
A= Force= Mass X Acceleration
Potential energy is:
- Energy from motion
- Stored energy
A= Stored energy
Potential energy depends on:
- Height and mass
- Mass and speed
- Friction and speed
A= Height and mass
A person or object may have stored energy because of its: (Multiple Choices)
- Mass
- Position
- Velocity
- Speed
A=
- Mass
- Position
The tendency of an object to stay in motion is called:
- Inertia
- Momentum
- Velocity
- Gravity
A= Momentum
Inertia depends on mass:
- True
- False
A= True
An object has kinetic energy if it is not moving:
- True
- False
A= False
