Acceleration

What does a negative acceleration indicate?

• The object is speeding up.

• The object is moving at a constant speed.

• The object is slowing down.

• The object is changing direction.

What is acceleration?

• The rate of change of velocity of an object.

• The force applied to an object.

• The distance traveled by an object in a given time.

• The speed of an object at a specific moment.

What does a constant speed mean in terms of acceleration?

• The acceleration is zero.

• The acceleration is constant.

• The acceleration is increasing.

• The acceleration is decreasing.

What is the formula for calculating acceleration?

• Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t).

• Acceleration (a) = (Initial Velocity (u) - Final Velocity (v)) * Time (t).

• Acceleration (a) = Final Velocity (v) * Time (t).

• Acceleration (a) = (Final Velocity (v) + Initial Velocity (u)) / Time (t).

How do you calculate the acceleration of an object that comes to a stop?

• a = (0 - Initial Velocity) / Time

• a = (Final Velocity - Initial Velocity) / Time

• a = (Initial Velocity - Final Velocity) / Time

• a = (Initial Velocity + Final Velocity) / 2

What does it mean if the acceleration is positive?

• The object is slowing down.

• The object is at rest.

• Positive acceleration means the object is speeding up.

• The object is moving in a negative direction.

What is deceleration?

• A term used to describe positive acceleration, where an object is speeding up.

• A term used to describe negative acceleration, where an object is slowing down.

• A term used to describe constant speed, where an object is maintaining its velocity.

• A term used to describe the change in direction of an object without changing its speed.

What does a steep slope on a position vs. time graph indicate?

• A low speed

• A constant speed

• A high speed

• A negative speed

If an object is moving at a constant velocity, what is its acceleration?

• Zero

• Constant

• Increasing

• Decreasing

What happens to the acceleration of an object if the net force acting on it is zero?

• The acceleration increases.

• The acceleration decreases.

• The acceleration remains constant.

• The acceleration is also zero.
