Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What does Newton's First Law of Motion state?

Back

An object at rest will stay at rest, and an object in motion will stay in motion with a constant velocity unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What happens to the speed of an object when a force is applied in the opposite direction of its motion?

Back

The speed of the object will decrease.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

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 vacuum chamber?

Back

A vacuum chamber is a sealed enclosure from which air and other gases are removed, allowing experiments to be conducted in a near-perfect vacuum.

Front

What is the role of gravity in motion?

Back

Gravity is a force that attracts two bodies towards each other, influencing the motion of objects, especially when they are falling.

Front

What is the formula for calculating force?

Back

Force is calculated using the formula F = ma, where F is force, m is mass, and a is acceleration.
