1D Motion Review

Front

What is a Scalar quantity?

Back

A scalar quantity is a physical quantity that has magnitude only and no direction. Example: Speed.

Front

What is a Vector quantity?

Back

A vector quantity is a physical quantity that has both magnitude and direction. Example: Velocity.

Front

Define Displacement.

Back

Displacement is the change in position of an object and is a vector quantity.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity - Initial Velocity) / Time.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately -9.8 m/s².

Front

How do you calculate the net force acting on an object?

Back

Net Force = Mass (m) x Acceleration (a).

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object and is calculated as Weight = Mass x Gravity.

Front

What does it mean for an object to be in free fall?

Back

An object in free fall is only under the influence of gravity, with no other forces acting on it.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object is moving, while velocity is a vector quantity that includes direction.

Front

What is uniform motion?

Back

Uniform motion occurs when an object moves at a constant speed in a straight line.
