Physical Science Final Exam Review

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) is calculated using the formula: a = (final velocity - initial velocity) / time.

Front

If a golf ball accelerates at 15 m/s², how does this affect its velocity over time?

Back

The golf ball's velocity increases by 15 m/s for every second it accelerates.

Front

What is the relationship between unbalanced forces and motion?

Back

Unbalanced forces cause an object to change its state of motion, either by accelerating or decelerating.

Front

Define net force in the context of physical science.

Back

Net force is the vector sum of all the forces acting on an object, determining its acceleration.

Front

What is the unit of measurement for acceleration?

Back

The unit of measurement for acceleration is meters per second squared (m/s²).

Front

How do you calculate the time taken for an object to accelerate from rest to a certain velocity?

Back

Time can be calculated using the formula: time = (final velocity - initial velocity) / acceleration.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the significance of a net force of zero on an object?

Back

A net force of zero means that the object is in equilibrium, and it will not accelerate; it will either remain at rest or continue moving at a constant velocity.

Front

Explain the concept of inertia in relation to forces.

Back

Inertia is the tendency of an object to resist changes in its state of motion; it is directly related to the object's mass.

Front

What is the formula for calculating speed?

Back

Speed (s) is calculated using the formula: s = distance / time.
