What is acceleration?

Back

Acceleration is the rate of change of velocity, which can involve increasing speed, decreasing speed, or changing direction.

What happens when forces are balanced?

Back

When forces are balanced, the object remains in place and does not accelerate.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.

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 a Newton?

Back

A Newton is the unit of force in the International System of Units (SI), defined as the force required to accelerate a one-kilogram mass by one meter per second squared.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

What is the formula for calculating acceleration?

Back

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

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.
