Forces and Motion Redemption

Front

What is Newton's 1st Law of Motion?

Back

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

Front

What is Newton's 2nd Law of Motion?

Back

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 3rd Law of Motion?

Back

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

Front

Define velocity.

Back

Velocity is the speed of an object in a specific direction.

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) = Change in velocity (Δv) / Time taken (Δt).

Front

How do you calculate the mass of an object using force and acceleration?

Back

Mass (m) = Force (F) / Acceleration (a).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight (W) = Mass (m) × Gravitational acceleration (g).

Front

What is the gravitational acceleration on Earth?

Back

The gravitational acceleration on Earth is approximately 9.81 m/s².

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.
