Physics Review

Front

What is force?

Back

A force is a push or pull that can cause an object to accelerate, change direction, or change shape.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, typically measured in meters per second squared (m/s²).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; an object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that cause an object to accelerate; they occur when the net force acting on an object is not zero.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) can be calculated using the formula: a = F/m, where F is the net force applied and m is the mass of the object.

Front

What is the relationship between force and motion?

Back

Force is directly related to motion; an increase in force results in an increase in acceleration, while a decrease in force can slow down or stop motion.

Front

What does it mean for an object to have constant velocity?

Back

An object has constant velocity when it moves at a steady speed in a straight line, meaning both speed and direction remain unchanged.

Front

What is the effect of applying a greater force to an object?

Back

Applying a greater force to an object will increase its acceleration, causing it to move faster or change direction more rapidly.

Front

What is the significance of the net force?

Back

The net force is the total force acting on an object after all the forces are combined; it determines the object's acceleration.

Front

How does mass affect acceleration?

Back

The greater the mass of an object, the less acceleration it will have for a given force; this is described by Newton's second law of motion.
